BOSTON -- The fan who threw a can onto the court during the third quarter of the Boston Celtics loss to the San Antonio Spurs has been banned from the arena for life.

“Last night, after throwing a can onto the court during a Celtics game, a guest was ejected from TD Garden. The guest was arrested by Boston Police and is currently facing criminal charges,” TD Garden spokesperson Tricia McCorkle said in a statement. “This act is a serious violation of our guest code of conduct and as a result the guest will be banned from all future events at TD Garden, for life.”

That fan has been identified as 22-year-old Justin Arnold of Everett. He reportedly threw a 20-ounce can of Truly Hard Seltzer from section 303, which landed just in front of the Spurs bench. No one was injured.

The incident happened in the wake of Kemba Walker’s ejection in the third quarter last night. Walker received two quick technical fouls during a Celtics run that had cut a 20 point Spurs lead down to seven. Emotions in the Garden were already high as the Celtics closed the gap, but the rapid succession of what appeared to be a foul on the Spurs, the Walker ejection, a separate technical foul on Brad Stevens, and foul on Daniel Theis caused tempers to boil over. It was in that moment that the can was thrown.

“I apologize to the Spurs for what happened out of the stands. And that can being thrown,” Stevens said after the game. "I told Pop after the game, I’m really sorry that they had to experience that. I hope that person’s not allowed in an NBA arena again.”

Gordon Hayward added, “we can’t have that... no matter what happens on the court, we can’t have anybody throwing stuff from the fans... I love our fans, love the passion that they bring. They certainly bring a lot of energy, but we’ve got to try to stay away from that.”

Arnold reportedly faces one charge of disturbing a public assembly.
