Police in Cambridge, Massachusetts, are urging students of the Massachusetts Institute of Technology to stay indoors as they hunt for a gunman who fatally shot a police officer late Thursday evening.
Campus police said the police officer was shot multiple times while responding to a disturbance on campus and later died of his wounds in the hospital.
A large area of campus has been cordoned off as security forces fan out to look for the suspect.
Cambridge is just across the Charles River from Boston, where twin explosions marred the prestigious Boston Marathon on Monday, leaving three people dead and some 170 wounded.
