Three people are in custody after a shooting on the Boston Common on Tuesday, according to police.
The shooting was reported just before 7 p.m. in the area of the bandstand.
The victim, a 19-year-old man from Hyde Park, was shot multiple times and he suffered life-threatening injuries. He remains in critical condition.
Police say two men fled on mopeds and another on foot. All three were taken into custody and are being questioned. Boston Police Commissioner William Evans referred to the men as "persons of interest."
"We need the public's help, obviously, there was a lot of people down here. Which is the troubling thing," Evans said. "We have a lot of work to do."
Evans added that the victim and all three people in custody were known to each other.
Emerson College, which is located near the Common, sent out an alert warning students and faculty about a shooting near campus.
"If you are on campus, go to the nearest available room and lock/barricade the doors and silence phone," the alert said. "If you are not on campus, stay away until further updates."
The MBTA was reporting delays on the Red and Green lines due to police action, but it wasn't immediately clear if this was connected to the shooting.
