Authorities say a campus police officer at the Massachusetts Institute of Technology has died from injuries in a shooting on the campus outside Boston.
Cambridge police and the Middlesex District Attorney's office says the officer was responding to a report of a disturbance when he was shot multiple times. He later died at a hospital. His name was not immediately released.
State police spokesman Dave Procopio says the shooting took place about 10:30 p.m. Thursday outside an MIT building.
Police at the Massachusetts Institute of Technology say a suspect in the fatal shooting of an officer is no longer on campus.
No arrests have been made in the MIT officer's shooting. The shooter is being sought.
But MIT said Friday on its website it's now "safe to resume normal activities."
Still, it's urging its 11,000 students to "remain vigilant." It had earlier warned them to stay indoors when the shooter was on campus.
The shooting comes just days after twin bombings at the Boston Marathon finish line killed three people, wounded more than 180 others and led to an increase in security in the region.
