Police and the Federal Aviation Administration are investigating an incident aboard a Los Angeles-bound Delta Airlines flight where a man allegedly attacked other passengers.

The incident occurred late Monday morning on Delta Flight 501 from Atlanta to LAX. The Los Angeles Fire Department reported that the adult male passenger had to be restrained after biting one passenger and hitting others.

The flight landed safely, and the unruly passenger was detained.

“Delta has zero tolerance for unruly behavior and worked with law enforcement authorities on the investigation,” a Delta Air Lines spokesperson said in a statement.
