BOSTON — House Democratic Whip Katherine Clark’s daughter has been charged with assault after an altercation with a police officer who was trying to arrest her for allegedly spray painting anti-cop messages on the Boston Common bandstand.

Riley Dowell, 23, who was identified in a police press release Sunday under the name Jared, which Clark’s office identified as her former name, was spotted defacing the bandstand with “NO COP CITY” and “ACAB” — “all cops are bastards” — during a protest Saturday night.

While she was being arrested, police said roughly 20 protesters began to surround officers, yelling profanities and disrupting traffic. During that time, an officer was “hit in the face and could be seen bleeding from the nose and mouth.”
