Justin Bieber has been accused of punching a man in the face after the stranger "grabbed a woman by the throat".
Justin Bieber has been a lot of things in his short time on Earth: a pop-star, actor, celebrity church enthusiast, and now, Woman Protector.
Justin and his friend screamed at the man to get off her, but when that didn't work he took matters into his own hands.
Inside sources at the party say the man who went insane on the woman appeared to be on drugs. When he refused to listen Bieber allegedly punched him in the face and pushed him against a wall, causing him to lose his grip on the woman's throat. The guy was reportedly then thrown out of the event and was soon after seen chasing an SUV that he apparently though Justin was inside of. Later, he was spotted shouting Justin Bieber's name and slamming on a vehicle. Cops eventually came and arrested him.
