12:16 PM PT -- Denver Police tell TMZ that the man in this video was NOT arrested and did not end up being booked for any charges as a result of the disturbance. He was merely treated at the hospital.
10:27 AM PT -- Denver PD tells TMZ ... officers at the airport responded to a call for a disturbance on an AA flight around 6:30 PM Friday night. We're told police on the scene determined the issue was more medical than anything else, and the unruly passenger was taken to a hospital.
It's unclear what his medical status is now, or whether the guy was ultimately arrested or not. The good news, though, is that there were no reported injuries to passengers, flight staff or police personnel. Looks like his crappy punch didn't land.
9:31 AM PT -- A rep for American Airlines tells TMZ ... "Flight 2408 diverted due to a disruptive passenger. Law enforcement met the flight, and the aircraft re-departed." They also thanked their crew members for taking care of their customers during the chaos.
An American Airlines jet made an unscheduled landing Friday after a passenger lit up a joint and got super aggro.
We're told the plane was going from Phoenix to Minneapolis, but an hour into the flight the pilot went on the intercom and said they had to make an emergency landing in Denver because of "a security issue in the back."
The passengers were a little freaked out, trying to figure out what was going on. The buzz in the cabin was that someone in the back said he was telling everyone around him, he was on cocaine. That's when the guy with dreads in the video ran to the back of the plane into the bathroom and locked the door.
Passengers tell us the flight attendants were super concerned and huddled around the bathroom door, trying to coax the guy out, to no avail.
We're told the guy was in the bathroom for 10 minutes and then, 5 minutes before the plane landed, he left the bathroom and went back to his seat. He was very jittery and, when the plane landed, cops and EMTs went onboard.
That's where the video starts ... you see the guy pull out a joint and a lighter, and start smoking. The pilot then came on the intercom and asked passengers in the first 13 rows to get off the plane, so they could remove the man. As they deplane, the guy punches one of the passengers.
You hear one passenger say there were Raiders fans onboard so they could take care of the guy.
Cops and EMTs removed the guy, handcuffed him and put him on a gurney. You hear him scream the cuffs were hurting him as he demanded to be freed, screaming, "Take it off, it hurts. I'll f***ing kill you!"
About 2 hours later, the plane was back up in the air ... en route to Minneapolis.
