A 16-year-old Revere girl was charged with assault and battery with a dangerous weapon in connection with an unprovoked attack on a 35-year-old woman on Tuesday, according to Suffolk County District Attorney Kevin Hayden.
The girl, whose identity was not disclosed by the district attorney’s office, was also charged with unarmed robbery for the attack on a Silver Line bus toward Nubian Square on July 2, officials said. She was arraigned Friday at Boston Juvenile Court.
The girl was part of a group of eight suspected juveniles who participated in the attack, officials said. She was seen on video hitting the woman’s head roughly seven times and kicking her in the head and face about three times, according to officials.
