An onlooker in the baggage check-in area at the Newark Airport captured the moment a United Airlines employee attacked a passenger, leading to a violent brawl.

According to DailyMail, the incident happened Sunday morning as a customer used a wheelchair to bring his baggage to the check-in desk. An unidentified United Airlines employee confronted the customer, then, according to a video provided by an onlooker, the pair began arguing before the altercation turned violent.

Witnesses said the employee appeared to have started the physical altercation, but the customer landed punches, sending the employee spiraling backward into luggage on the check-in conveyer belt.

TMZ reports that the customer was ultimately arrested for the brawl. It’s unclear if the employee will face any charges.

A United Airlines spokesperson told DailyMail that violence will not be tolerated by any employees but declined to expand further.

“United Airlines does not tolerate violence of any kind at our airports or on board our planes and we are working with local authorities to further investigate this matter.”
