The Cambridge police reported that multiple shots were fired and explosives were detonated in Watertown, as per The Tech, MIT's oldest and largest newspaper.

David Procopio, a spokesman for the Massachusetts State Police, said the motive for the shooting was not known and the investigation would be led by the Middlesex County District Attorney's Office after the death of the officer.

One of the two suspects was brought into custody first, after which the MIT website said that another "suspect remains at large. Please continue to stay indoors. Updates at emergency.mit.net".

Cellphones have been ordered to be switched off because the cops fear that they could trigger explosives that are suspected to be in the area.

The second suspect was later asked to surrender. He was on the ground, flat on his face but the police were not walking towards him because they believed he had explosives on his body, reports CNN. They later asked him to undress completely and arrested him.

The FBI is now at the scene to investigate.
