Bench Warrant Issued for Lindsay Lohan

A judge just issued a bench warrant for Lindsay Lohan's arrest, after she failed to show up in court this morning ... and the judge says she has reason to believe Lindsay has a drug and alcohol problem.

Judge Marsha Revel was tough as nails this morning, scoffing at the notion that Lindsay's "someone-stole-my-passport" excuse was a justification for missing court. 

Judge Revel set bail at $100,000 and said Lindsay can post bail and remain free until the next court hearing, IF she does the following:

- Drink no alcohol
- Wear a SCRAM bracelet
- Submit to random drug testing at least once a week

Lohan's lawyer, Shawn Chapman Holley, told the judge the story TMZ broke -- that Lindsay claimed her passport was stolen and she tried getting on a flight to make it on time but was turned away.

At one point Holley said, "I don't know what else to tell you."

But the judge didn't buy Lindsay's argument, saying "Actions speak louder than words."  The judge felt Lindsay could have gotten a replacement passport and made it back on time.  And, the judge said Lindsay had "a history of not keeping scheduled appointments."

Holley said there was no reason to require drug testing, but the judge noted that Lindsay was charged in 2007 with being under the influence of cocaine.

Judge Revel said Lindsay knew she was going to jail if she violated probation and knew she needed to get court approval before missing her alcohol ed classes.  After the hearing Holley acknowledged what TMZ first told you ... that Lindsay has only completed 10 of the required 13 classes.

The judge said there is probable cause to believe Lindsay has violated her probation.  If the judge determines Lindsay did indeed violate probation she could be jailed for 180 days.
