DUI

Chris Kattan was arrested for DUI early this morning after his car struck a vehicle ... and TMZ has learned he allegedly confessed he was on prescription meds.

Law enforcement sources tell TMZ ... the former "Saturday Night Live" cast member was arrested on the 101 Freeway in the San Fernando Valley just after 1 AM.

Another driver called CHP to report another driver in a Mercedes who was "weaving all over the roadway at slow speeds."

Kattan allegedly then crossed into an area that was coned off for a freeway closure and he struck a Dept. of Transportation vehicle from behind.

Kattan was not injured and apparently there was no one in the DOT vehicle.

Cops say Kattan appeared out of it. Our sources tell us he was arrested and booked for DUI ... specifically drugs, NOT alcohol.

Prosecutors in the Justin Bieber Miami Beach misdemeanor DUI case are hunting down witnesses across the country ... including Bieber's own girlfriend ... in an attempt to nail him.

Sources connected with the investigation tell us ... investigators have been hounding Chantel Jeffries and her friends and relatives, trying to get her to sing like a bird and incriminate the Biebs.

Sources in the State Attorney's Office tell TMZ ... it's not unusual for them to go on the hunt for witnesses, even though this is a routine DUI misdemeanor case.

But here's what we know. If they get to Chantel, she's not going to help their case. We're told she is clear -- Justin did NOT drink or smoke weed in the club before getting in the Lambo. She also insists the drag racing claim is total BS -- that they never went faster than around 40 MPH.

TMZ broke the story ... prosecutors have problems with the case. First of all, cops claimed Bieber reeked of booze in the car and when he was at the station, but he registered an imperceptible .014. And as for the drag racing claim ... the GPS readout shows the max speed at 44 MPH, and during the so-called drag race he was going 27 MPH -- below the speed limit.

So we gotta ask ...

The mother of Paul Walker's 15-year-old daughter appears to have serious alcohol issues -- TMZ has learned, she was arrested for DUI in August and that wasn't her only one -- and it's a major reason why Meadow moved away from her mom to live with Paul.

Rebecca Soteros was first arrested for DUI in 2003 in Orange County. She pled guilty and was sentenced to 3 years probation.

History repeated itself last year, when Soteros was arrested again for DUI in Hawaii. That case is ongoing.

Sources close to the family tell TMZ ... Rebecca's drinking has been an ongoing issue for years. Paul's daughter Meadow called her famous dad in 2011 and pleaded to let her move to L.A. and live with him. He happily obliged, because we're told Paul and Rebecca had countless arguments for years over her drinking problems.

Justin Bieber clearly thought he was too cool for school when cops busted him in Miami Beach last month -- and in surveillance footage released by cops ... he isn't just pacing behind bars ... he's strutting.

Justin looks like he's been thoroughly put out by the DUI arrest ... his head cocked back during the wee hours of the morning.

You see Justin get patted down by cops ... but they found nothing.

The gay singer from "Nick & Norah's Infinite Playlist" didn't just brutally attack his real-life GF before his double arrest in December ... he also destroyed her bedroom and threatened multiple times to kill ... this according to the police report obtained by TMZ.

Rafi Gavron's GF told cops, the December 14 argument was triggered by Rafi's cocaine problem -- he demanded money from her and she refused ... so he went ballistic.

The GF said she hid her money and credit cards in her bedroom. In retaliation, Rafi punched her with both fists and slapped her across the face several times, then pushed her to the ground and kicked her in the stomach.

The GF says it wasn't over ... Rafi destroyed her bedroom, ransacking her dresser and closet and then kicking her mirror, breaking it. When she tried to phone police, she says Rafi grabbed her phone, threw it on the ground, shattering it to pieces, and repeatedly threatened to kill her.

The girlfriend says she managed to escape and ask a neighbor to phone police ... but Rafi took off in her car. She was taken to a nearby L.A. hospital with minor injuries, including marks on her legs and back.

As we reported, Rafi was subsequently pulled over in his girlfriend's car and arrested for DUI. Hours later he was released from jail hours and immediately arrested AGAIN for domestic violence.

He was charged with 4 felonies ... dissuading a witness from reporting a crime, false imprisonment by violence, domestic violence and joy riding. He copped a plea and pled no contest to domestic violence and joy riding. He was placed on 5 years probation.

David Cassidy has just been charged with one count of driving under the influence of alcohol ... the L.A. City Attorney's office tells TMZ.

We broke the story ... Cassidy was arrested in L.A. Jan. 10th after cops say he made an illegal right turn. We're told he had alcohol on his breath ... and failed a field sobriety test.

Law enforcement sources tell us he blew a .19 in the field -- more than twice the legal limit -- and refused to submit to more testing back at the police station.

Cassidy has a prior conviction for DUI in FL ... and a DUI arrest in NY. According to the city attorney, that means he'll serve a mandatory 96 hours in jail if convicted this time ... and could face up to a year behind bars.

Justin Bieber's days of breezing in and out of the U.S. are over ... because we're told he will continue to be a target of U.S. Customs every time he comes back to the states.

TMZ broke the story ... when Justin flew into a New Jersey airport from Canada last Friday ... U.S. Customs searched his plane and then grilled him for hours, before letting him leave. Law enforcement sources tell us ... Custom's flagged Bieber because he's on a Homeland Security watch list for his 2 ongoing criminal cases.

We're told Bieber is subject to the exact same treatment every time he leaves and then re-enters the U.S. -- a thorough search and then exhaustive questioning.

It's very hard to get off the watch list once you're on it. You can appeal to Homeland Security but the agency has broad discretion. What's more ... if Bieber is found guilty or pleads no contest to any criminal charge, it will be extremely difficult for him to go under the radar again.

The DUI case against Justin Bieber has some big holes -- but law enforcement sources tell us prosecutors will NOT back down and are confident the case is so strong ... Justin will cop a plea.

TMZ broke the story ... although Miami Beach police claimed Justin reeked of booze ... his blood alcohol level was almost imperceptible -- .014.

Sources connected to the case tell us ... prosecutors say the officer who made the observation is a star witness who is one of the most authoritative people in the area on DUI -- and an unimpeachable witness.

There's another hole in the case. Cops claimed Justin was drag racing, yet we've obtained the GPS read on his car and it actually shows in the middle of the so-called drag race he was going 27 MPH -- UNDER the 30 MPH speed limit.

Our sources say they're not buying the GPS read out and they have their own GPS which they believe will show a higher rate of speed.

We're told Bieber has just been released by Custom's officials ... after 5-hours of heavy grilling.

Justin Bieber was flagged by U.S. Customs officials when he landed in New Jersey this afternoon because he has 2 pending criminal cases ... law enforcement sources tell TMZ.

Bieber is still being grilled by Customs people ... after they searched his plane because they allegedly smelled weed. The search turned up nothing.

We're told -- as a result of the Patriot Act -- Customs officials have broad power to flag people coming in from another country when they have an active criminal case or a conviction. Justin currently has an assault case in Canada and a DUI case in Miami Beach.

Sources say Bieber is being "put through the grinder" right now by Customs folks. As one source said, "Once you're flagged it's a grueling process to get in the country."

It's almost certain Justin will eventually be cleared to leave Teterboro Airport because both alleged offenses are minor.

Stone Cold Steve Austin just threatened to open a can of WHOOP-ASS all over Justin Bieber ... warning the pop star that if he doesn't straighten up, he's gonna catch a Size 13 in his ass.

The former WWE champ was on "The Arsenio Hall Show" last night when he issued the ultimatum -- shape up ... or else.

Stone Cold says he loves kids ... and just wants to make sure Justin gets on the right path before it's too late -- but he thinks an ass-kickin' is the only thing that'll get through to the Biebs.

TMZ has obtained GPS records from the rented Lambo Justin Bieber was driving when he was arrested for DUI ... and there is NO evidence of drag racing.

TMZ broke the story ... Miami Beach cops claimed they noticed Bieber and his buddy Khalil (who drove a red Ferrari) drag racing and that's why they were stopped. Cops claimed they were going between 55 and 60 MPH.

But the GPS on Justin's car records speed when the car accelerates quickly. Take a look at the read-out. At 4:07 AM Justin left the club and zoomed away ... reaching a maximum speed of 44 MPH. Two minutes later the GPS registered at a max speed of 27 MPH.

Here's why the read-out is so significant. Cops claim they noticed the drag race on the 2600 block of Pine Tree Drive. Bieber came to a stop and was then arrested on the 4100 block. The 27 MPH read out is on the 3700 block ... smack in the middle of the supposed drag race. Mind you ... 27 MPH is UNDER the 30 MPH speed limit.

If Justin had been racing ... the GPS would have recorded a higher speed. Yet the maximum speed on Pine Tree was 27 MPH.

Now check this out. The cops say 2 Escalades were stopped on Pine Tree to block traffic so Bieber and his buddy could drag race. We obtained the GPS for one of the Escalades (below) which shows at 2:35 AM the SUV stopped -- and that's when Bieber's dad (who was in the Escalade) went inside the nightclub with his son. They were there for 1.2 hours.

At 4:06 AM the Escalade started rolling and it didn't stop again until Bieber was pulled over. So it never stopped to accommodate a so-called drag race.

Senator Marco Rubio has got big fish to fry ... nonetheless, he's kinda worried about Justin Bieber.

Rubio stopped in the Dirksen Senate Office Bldg in Washington D.C. to chew the fat with us ... and the father of 4 has a clear view that the Biebs is in trouble and needs help.

The Justin Bieber toxicology report from his DUI arrest in Miami Beach is in ... and it shows he tested positive for marijuana and prescription medication, TMZ has learned.

According to the report -- obtained by TMZ -- Justin's urine was tested right after he was busted for driving under the influence on January 23 ... and it shows there was THC and Alprazolam in his system.

FYI -- Alprazolam is the key ingredient in Xanax (prescription anti-anxiety medication).

The report also shows Justin tested NEGATIVE for cocaine, opiates, meth and other drugs.

The report is consistent with the police report where cops say he told them his mom had provided him with prescription pills.

As for the weed, Justin also told cops he had been smoking pot in his recording studio all night long.

Bieber has pled not guilty to the charges.

Justin Bieber was "excited, talkative, insulting, cocky" and profane when he was arrested in Miami Beach last week ... this according to official police documents.

According to the docs, a cop at the scene claimed Bieber "reeked of marijuana." Cops say Bieber's reaction was this ... "Yeah, we were smoking all night at the studio."

The officer claims Bieber was initially open to taking a "breath test" but then had a change of heart, asking the cop what would happen to his license if he refused the test.

The cops say Justin was out of it and couldn't follow basic instructions on how to provide the breath sample. The docs say "he had extreme difficulty providing a continuous breath."

The report also says Bieber wasn't blowing into the tube properly and cops thought he was deliberately undermining the test. Bieber then became "agitated" and told the officer he was "blowing into the hose like he blows into his trumpet."

Cops say he admitted he took medications for anxiety, saying "My mom takes care of all that stuff for me."

As TMZ first reported, the docs say Bieber blew a .014, which is barely perceptible.

And cops say he flunked the field sobriety test miserably -- his balance was off, he would sway, he couldn't smoothly follow a moving object and couldn't do the finger to nose test with his eyes shut.

The rented Lambo Justin Bieber was driving before his DUI arrest is now practically a celebrity itself -- in fact, so famous ... it's become a Holy Grail for Bieber fanatics and modeling shoots.

Good example ... here's 24-year-old Miami smokeshow Madison Murray rubbing her ass on the car at a showroom on Tuesday.

Sure, it's a yellow Lambo -- who wouldn't want to pose beside it -- but sources tell us, Justin's car has made such a reputation for itself this month ... local models are practically clawing at each other to get a photo op.

And it's not just models ... a source at Miami's Lou La Vie exotic car rental -- which owns the whip -- tells us, the company's been inundated with calls from crazy Bieber fans too ... asking to rent it just for a day to take photos at the DUI arrest site.

It ain't cheap though ... the car rents for $1,500-$1,700 a day, depending on how many days you rent it for. So far, it's already booked through this weekend.

Get in line, Beliebers.

Justin Bieber will FIGHT charges in Miami Beach that he resisted arrest, was driving under the influence and driving with an expired license ... he has pled not guilty.

In Miami Beach, being arrested for a misdemeanor is equivalent to being charged. Justin's arraignment is scheduled for Valentine's Day, but his lawyer, Mark Shapiro, has entered a written not guilty plea.

Bieber will still be arraigned but is not required to be present in court.

Law enforcement sources tell us ... they could still add charges before the arraignment.

TMZ broke the story ... prosecutors are going to have problems because Justin's blood alcohol level was imperceptible -- .014 -- yet they claim he reeked of booze. Cops also say he was drag racing yet the GPS readout shows he was not.

As we reported ... Justin will be charged in Toronto with assaulting a limo driver. And he's also being investigated for egging his neighbor's house, and that could be filed as a felony.
