New York Police Department tells Us Weekly the "Transformers" star was live streaming his anti-Donald Trump “He Will Not Divide Us” protest when he got into an altercation with another man.

“His victim was a 25-year-old male,” the police officer confirmed. “For whatever reason, Shia grabbed his scarf that was tied around his neck and head, and pulled him to the ground. The man was left with scratches on his face and red marks around his neck.”

Although the man refused medical treatment, the 30-year-old actor was arrested and charged with misdemeanour assault.

Shia has been released but will have to appear in court at a later date.
