Authorities say a campus police officer at the Massachusetts Institute of Technology has died from injuries in a shooting on the campus outside Boston.
No arrests have been made and a manhunt is on for the shooter.
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. outside an MIT building.
Procopio says authorities are searching for a suspect or suspects.
There are no other victims.
About 11,000 people attend the prestigious school.
The campus website said police were sweeping the campus and urged people to stay indoors.
