Authorities in Santa Clara, California are preparing to respond to a video of three local officers hitting and threatening to use a Taser against a man during a college football game, the San Jose Mercury News reported.

The video, taken during the Pac-12 championship game on Dec. 5, shows the officers’ rough arrest of a man later identified as Mark Lydon, an Oregon resident visiting for the game. The department confirmed to Deadspin that its officers were involved in the altercation.

KGO-TV reported that Lydon was charged with assaulting an officer and resisting arrest. A department spokesperson said Lydon attacked the officers while they were trying to eject him from Levi’s Stadium, where the game was held, when the altercation took place.

According to the unidentified man who filmed the encounter, however, the incident began after one officer saw Lydon walking the wrong way down a stadium concourse.

The person filming the encounter tells the officer, “I don’t know [Lydon] at all.”

“I don’t care,” the officer responds.

“This is crazy,” the man says. “You have your Taser out, there’s a huge crowd. Don’t touch this guy.”

“Leave him alone,” the man filming yells. Another man can be heard in the background saying of Lydon, “He’s not fighting back.”

The video shows Lydon’s head and neck being held by one officer, while the other two grab his arms before taking him to the ground. Other officers arrive and instruct the man filming and the crowd watching the arrest to keep back.

“I have the video from the beginning,” the man filming says. “That guy didn’t do anything wrong.”

Another person can be heard saying, “Just don’t choke him, you f*cking cops,” a reference to the death of Eric Garner, which was ruled a homicide by choking after his encounter with New York City police this past July.

The Mercury News reported that Santa Clara police regularly work security for events at the stadium, sometimes supplemented by officers from other nearby departments who are specially deputized to work there if a larger event is taking place.
