Police have surrounded UMass Boston after reports of an active shooter, authorities say.

“Troopers have responded to UMass Boston to an unconfirmed report of a shooting on campus,” the Massachusetts State Police wrote in an X post. “Law enforcement will coordinate with our campus partners to ensure the safety of students, faculty, and staff.”

A Boston Police spokesman confirmed to the Herald that the department had also responded to the call which came in at 3:43 p.m.

BPD Officer Michael Torigian described the scene as “very active.”

The school itself said that there was a “police incident in/near Campus Center” and to avoid the area. Earlier its official X account posted that there was a “Public Safety threat in/near Residence Hall East Building.”

This is a developing story.
