The Massachusetts Bay Transportation Authority (MBTA) Transit Police are on the lookout for a person of interest linked to an assault and battery case involving a juvenile male victim. The incident, which unfolded on July 24th around 2PM at the Sullivan Square station, was serious enough to publicly solicit for aid in identifying a potential suspect. According to a post on the MBTA Transit Police’s official social media account, the young victim was attacked and hit multiple times with closed fists.
