A man who was shot several times with pepper balls during this weekend’s post-NCAA tournament game riot in Tucson, Ariz., has been identified as Alex Davidson.

The Tucson Police Department used force to disperse a massive crowd of students who began to riot after Arizona’s 64-63 loss to the University of Wisconsin on Saturday, the Daily Wildcat, Arizona’s student newspaper, reports. Clad in riot gear, the officers used pepper canisters and shot pepper balls at fans, who responded by throwing beer bottles and smoke bombs at police.

“We gave the dispersal order several times, both in English and Spanish, telling everybody that the street had to be cleared,” Tucson Police Department spokesperson Sgt. Pete Dugan told the newspaper. “People were still refusing to leave, which at that point becomes a misdemeanor offense.”

The Tucson riots were the subject of several viral videos this weekend, one of which featured a young man who continued to walk toward police as they fired several pepper balls directly into his stomach. The man, identified as 23-year-old Alexander Davidson, was dubbed the “Terminator of Tucson” by Deadspin for his antics. It’s not clear if he is a current or former student at the university.

In the video, Davidson absorbs the pepper balls without any discernible reaction to the pain, Metro reports. He appears to taunt local police, who rush forward and place him under arrest. The “Terminator of Tucson” was one of 15 people taken into custody by police, the Daily Wildcat notes. Of the 15 people, nine are current students at Arizona.

On Sunday afternoon, an image posted to Twitter revealed the extent of the damage done to Davidson’s stomach. The 23-year-old suffered several burn-like marks on his stomach, but is no longer in police custody. Dozens of bystanders were stuck by pepper balls, the Daily Wildcat notes.

On Monday morning, Chris Sigurdson, the University of Arizona’s senior associate vice president of university relations, said that the school would investigate which students had committed actions that violated the institution’s honor code. “Obviously the students who obeyed the police orders are not in trouble,” Sigurdson said. “But for any student that may have been arrested or identified…the Dean of Students will call him or her in for an interview and then make a determination.”
