The passenger is facing charges of second-degree assault and second-degree assault on a peace officer.

The Transportation Security Administration (TSA) is asking for passengers "to remain calm and respectful" after an incident at Denver International Airport (DIA). On June 14, a passenger allegedly bit two TSA agents while attempting to go through the security checkpoint.

Keswan Hawkins, 29, was arrested by the Denver Police Department and faces charges of second-degree assault and second-degree assault on a peace officer.

Reports indicate that a probable cause document, which had been heavily redacted, said that Hawkins allegedly tried to go through the x-ray monitor, however, TSA advised he couldn't go through. This resulted in Hawkins swinging at the TSA agent "with a closed punch." In an effort to prevent the punch from connecting, the agent put his arm on Hawkins' chest, and then Hawkins began screaming. 

A struggle took place, culminating in Hawkins hitting another agent in the mouth and biting both agents in the leg.

This is one of two separate incidents that TSA has reported in the last month; another incident between a passenger and TSA occurred in Louisville, Kentucky.

According to a press release, the Kentucky incident saw "a passenger allegedly assaulted two TSOs while attempting to breach the exit lane and is facing state criminal charges for criminal trespass, fleeing and evading police, misdemeanor assault, and resisting arrest."

Both passengers in these incidents are facing a potential civil penalty (up to $13,910 for each violation of TSA security requirements).

In light of these incidents, TSA has announced steps to deter assaults against officers and flight crew members—Federal Air Marshals will begin flight crew self-defense training in July.
