at a Coachella party.
TMZ reports that the singer was at a Coachella party on Saturday when a man "went ballistic" and allegedly grabbed a woman by the throat. Justin hopped in, yelling at the man to let the woman go, but the man refused to and allegedly told Justin to "go fuck yourself." Justin then "hit the man in the face and pushed him against the wall… allowing the woman to break free."
TMZ added that the man appeared to be "under the influence of drugs," and that later he chased after an SUV he believed was carrying Justin. The report says he hit the side of the car and yelled Justin's name.
Cops arrived and the man was eventually arrested.
Justin has been at Coachella for the past couple of days, enjoying himself with friends.
