One of those wounded was critical and in surgery, said Boston police superintendent Bernard O’Rourke at the scene around 3:30 a.m. after police responded at around 2:15 a.m.

Upon arriving at the scene in response to a report of a fight, officers found the victims who had been stabbed with knives and bottles, O’Rourke said.

O’Rourke said authorities have identified a suspect.

Emerson College sent multiple alertsto its students, including a text message at 3:11 a.m. stating that two suspects were at large.

However, later at the scene,O’Rourke, said that one victim, “who did survive some wounds,” is believed to be the suspect.

The suspect fled the scene by way of Charles Street South, O’Rourke said.

Emerson College, which has a number of facilities nearby, said in one of the alerts that no members of the Emerson community were involved, and asked students to report any “suspicious activity.” Any witnesses are asked to call police at 800-494-TIPS.
