A passenger on an American Airlines flight heading to Philadelphia caused a disturbance in the final minutes of the journey after allegedly biting another traveler and trying to fight people on board.
The incident happened Sunday on a flight from Charlotte, North Carolina, as the aircraft was nearing Philadelphia International Airport.
Air traffic control audio reviewed by CBS News revealed the pilot described a passenger who appeared to be acting aggressively toward others on the plane.
"I don’t know … if he’s hallucinating or whatever, but he just bit a passenger and he’s trying to fight everybody. What a day, huh," the pilot said.
The pilot then asked for emergency medical personnel and law enforcement officers to be waiting when the flight arrived.
American Airlines later told CBS News that the passenger was experiencing a medical emergency.
A medical professional who happened to be on board stepped in and assisted the passenger before the aircraft landed safely.
The airline also confirmed that medical teams met the passenger after arrival, but did not say whether police officers were present when the plane reached the gate.
The incident comes amid a series of passenger disturbances reported on commercial flights in recent weeks.
