ROCHESTER, N.Y. — A man was shot and killed by a police officer in Rochester early Wednesday after he threatened officers with a knife, authorities said.

Capt. Mark Mura of the Rochester Police Department tells the Democrat and Chronicle that the shooting happened shortly before 3 a.m. near the Open Door Mission, a homeless shelter.

Mura said the man grabbed a large knife from inside the mission, left the building and was threatening to harm himself and others.

The man was threatening officers who had responded to the scene and moved towards them, Mura said. One officer fired at least one round, striking the man, he said.

Police said the man, whose name was not released, was taken to Strong Memorial Hospital, where he was pronounced dead.

Mura said he did not believe that the man was staying at the shelter. "The investigation is in the very preliminary stages at this point," he said.

The police department in Rochester, the third-largest city in New York state, has been under fire for months over the death of Daniel Prude  after he was restrained by police and more recently for pepper-spraying a 9-year-old girl.
