A Massachusetts Institute of Technology police officer was shot and killed Thursday night while investigating a disturbance on the Cambridge, Mass., campus, officials said.
There were reports of shots fired at 10:48 p.m. ET, and the situation remained "active and extremely dangerous," according to MIT's emergency website.
The situation remained "very fluid" after midnight, as police continued to sweep the campus.
Police were still looking for a suspect and no arrests had been made as of early Friday, according to the Middlesex County District Attorney’s office.
The area around the school’s Building 32 was cordoned off and students and staff were warned to "stay clear of area until further notice."
Massachusetts State Police were assisting Cambridge and MIT police in the investigation.
"No arrest has been made and the search for a suspect or suspects is ongoing," read a statement from the Massachusetts State Police.
The officer was responding to a report of a disturbance in the area of Vassar and Main streets, police said, when he was shot. According to authorities, the officer sustained multiple gunshot wounds. He was transported to the hospital and pronounced dead.
Cambridge is right across the Charles River from Boston, but authorities cautioned that there didn’t appear to be a link to the bombings earlier this week.
