(AP) – A man has been arrested after witnesses reported that he became unruly while aboard a Southwest Airlines flight.

Southwest Airlines spokesman Brad Hawkins said he couldn’t confirm early reports that the man tried to break into cockpit of Flight 3683. However, he said the crew of the Los Angeles-to-Kansas City flight decided on an unscheduled landing about 3:30 p.m. Tuesday in Amarillo as a precaution. There, the unruly passenger was turned over to federal authorities for questioning.

Hawkins said none of the 136 passengers and five crew members was injured, and that the passengers were to continue their trip aboard the same aircraft.

Transportation Security Administration spokeswoman Sarah Horowitz says information is still being gathered, and Amarillo Aviation Director Patrick Rhodes didn’t immediately return a message from The Associated Press.
