A man was arrested at Los Angeles International Airport on Wednesday for assaulting a flight attendant on a plane traveling from Mexico. Alexander Tung Cuu Le, 33, is due in court Thursday after he was caught hitting a flight attendant in the back of the head in a video shared on social media, CBS News reported. Witnesses said Le began acting erratically within 20 minutes of departing Los Campos International Airport, including wandering away from his seat and threatening violence against staff. The unruly behavior escalated when he punched a flight attendant who was trying to report him, according to video and an affidavit of the complaint against Le. Le was arrested upon landing and taken into custody by the Federal Bureau of Investigation, as the incident occurred in the air and involved the alleged federal offense of interfering with a flight crew. In a statement released Thursday, American Airlines said Le is barred from flying with the carrier in the future. “Acts of violence against our team members are not tolerated by American Airlines,” the statement said. “The person involved in this incident will never be allowed to travel with us in the future and we will be working closely with law enforcement in their investigation.” The airline continued to thank the crew and passengers for containing Le until the plane was met by law enforcement at LAX. “We thank our crew for their quick action and professionalism to ensure the safety of our fellow team members and customers on board,” the statement continued. “Our thoughts are with our injured flight attendant and we are making sure they and their crew members have the support they need at this time.”
