A violent passenger was arrested on Wednesday night for assaulting a flight attendant while traveling from Cabo to Los Angeles International Airport on an American Airlines (AA) flight.

The flight departed from Los Cabos International Airport in San José del Cabo, Mexico en route to Los Angeles International Airport (LAX). Circulating video shows the flight attendant walking away from the suspect while the flight was mid-air. 

After the employee's back is turned, the assailant is seen running up to the victim and punching him in the back of the head.  The suspect then jumps around erratically before walking back to his seat.
