EVERETT, Mass. -- A bicyclist who was struck by an Everett police officer responding to a 911 call has been identified, Everett police chief Steven Mazzie said.

Reda Rouf, 19, of Everett, was riding his bike down Glendale Street, when he was struck by the officer at about 8 p.m. Tuesday on Ferry Street. The officer had his cruiser's lights on at the time of the crash.

"I saw the cop put his lights on over there and then this guy (on the bike) came speeding down the hill and he never stopped,” said witness Genrii Rosario.

The bicycle flipped over the top of the cruiser and Rouf landed on the sidewalk just feet way, witnesses said.

Witnesses said the officer had the green traffic light in his favor.

"The cop was just holding the man's pulse and he was yelling 'I'm losing his pulse. I'm losing his pulse.' Someone covered him with a blanket, and the cop was crying. He was so upset," said Alli Cromwell.

Rouf, who was not wearing a helmet at the time of the crash, was taken to Massachusetts General Hospital, where he was listed in critical condition.

Everett police had issued a press release Thursday in which the department erroneously stated that Rouf had died. The department has apologized for issuing incorrect information.

“Our thoughts and prayers are with the family,” said Mazzie.

The police officer also needed treatment.

"He's shaken up a lot. He's a young officer. He's shaken up and went to the hospital as well," said Mazzie.

Police did not release the name of the officer. The incident is under investigation by the Massachusetts State Police.
