Maryland police arrested a 60-year-old man on Friday after he was captured on video assaulting a group of people, including a girl, who were reportedly putting up signs protesting the police killing of George Floyd .

The man, Anthony Brennan III, was charged with three counts of second-degree assault, according to the Maryland National Capital Park Police.

In a press release Friday , police said that Brennan was arguing with a group including two females and one male as they were posting flyers that included a call for community action.

Brennan forcibly grabbed the flyers from one of the victims, then pushed his bicycle toward the male in the group, causing the victim to fall, according to police.
