Update: Man Arrested in Brutal Videotaped Beating of Tourist in Baltimore

A man has been arrested in connection with last month's brutal beating of a tourist in Baltimore after viral video of the incident showed his alleged involvement.

Aaron Jacob Parsons, 20, turned himself in Friday night and has been charged with robbery and assault, according to the Baltimore Sun, which detailed the footage:

In the video, filmed the night of St. Patrick's Day, the seemingly disoriented victim is standing with a group of young people in front of the east building of the Clarence M. Mitchell Jr. Courthouse. As a girl dances against him, a man who police now say is Parsons grabs something out of the victim's pocket. The man moves to recover his property, and the man identified as Parsons rears back and punches him in the face, knocking him to the ground. The victim is then stripped of his clothing and teased.

Investigators had turned to the local and online community to identify those involved, the Sun reported. Parsons was identified on social media sites as one of the assailants and his personal information was spread across the Internet.

Parsons' attorney, Warren Brown, told the newspaper he's a "good kid" and is not responsible for the acts in the video that drew the most outrage.

"It's not the punch that has aroused so much anger — it's the humiliation after the punch, the disrobing of the guy and going through his pockets," Brown said. "He wasn't involved in any of that and has no real association with those people."

Police are still trying to identify the other attackers involved.
