NYPD Officer, 2 Bystanders Hit when Officers Shoot Armed Suspect on Subway Platform

An NYPD officer and two bystanders were shot at a subway station in Brooklyn Sunday afternoon when police opened fire on a man armed with a knife, authorities said. The suspect was also shot.

Four people -- one police officer, two civilians and the suspect -- were hospitalized, according to the FDNY. Interim Police Commissioner Tom Donlon said the wounded officer, who was shot in the chest area below his left armpit, is at Brookdale Hospital and "is in good spirits and is expected to make a full recovery."

The suspect, who officials said has more than 20 prior arrests and a significant history of mental illness, was shot multiple times. A 49-year-old man was struck in the head and is listed in critical condition at Kings County Hospital and a 26-year-old woman was grazed and was being treated at Brookdale Hospital, police told CBS .
