Three juveniles were arrested Monday evening after they allegedly beat a man near the JFK-UMass MBTA station. The Boston Police bicycle unit, returning from duty at the Boston Marathon, made the arrests- with a major assist from a helpful witness who tracked the suspects as they attempted to make their escape.

The incident took place at 6:45 p.m. near the corner of Harbor View and Spring Garden streets. The trio of hooded suspects— all described as between 16 and 18 years of age — threw the victim to the ground and kicked and punched him as they attempted to rob him, according to witness reports. A person driving by saw the attack in progress and yelled out to the group, at which point the attack stopped and the assailants walked down Sydney Street towards the MBTA station.
The witness trailed the suspects in his vehicle and gave police specific directions on their whereabouts, leading the bike unit to make the arrests at the intersection of Grant Street and Crescent Ave. The victim positively identified the suspects as the teens who assaulted him. They have been charged with unarmed robbery.
Captain Richard Sexton, commander at Area C-11 police district, praised the assistance of the “good citizen” who helped guide police.
