WATCH: Video shows passenger assaulting American Airlines attendant in Cabo to LAX flight

An American Airlines passenger was arrested on Wednesday, September 21, after he punched a flight attendant during a flight from Mexico to Los Angeles.

A video captured by a passenger onboard flight 377 showed a heated argument mid-air that ended with a man striking the flight attendant in the back of the head.

After the plane landed in Los Angeles, the FBI arrested the man for assaulting a crew member on the flight.

This is the second incident this month that involved an unruly American Airlines passenger. Earlier this month, 61-year-old Timothy Armstrong of Las Vegas, was arrested for screaming at a flight attendant on a flight headed to Salt Lake City International Airport.

The passenger turned aggressive towards the crew member when denied access to the first class bathroom

In the video, the passenger can be seen being combative with a flight attendant standing in the middle of the aisle. During the argument, the flight attendant can be heard asking the man if he was threatening the attendant. As the attendant walks away from the passenger, he mumbles, "Yeah, that's a no."

That is when the passenger runs behind him and strikes him in the head, shocking others on the flight.

According to ABC News, the altercation ensued after the passenger was stopped from using the first class bathroom by the flight attendant.

Following the assault, the man was restrained by other passengers and cabin crew. Authorities were reportedly waiting to arrest the man at the airport gates.

The man's identity wasn't disclosed by the time this article was written.

“Acts of violence against our team members are not tolerated by American Airlines. Our thoughts are with our injured flight attendant, and we are ensuring that they and their fellow crew members have the support they need at this time.”

According to NBC News, the FBI confirmed that the person was detained following an altercation on a flight from Mexico to Los Angeles.
