A Queens man was shot and killed by police officers Thursday night after he refused to drop a knife he used to stab himself and critically injure his wife, according to law enforcement sources.

Police were called to the building in Oakland Gardens at about 8:30 p.m. after an 18-year-old woman called 911 to report her father was stabbing himself, according to sources.

By the time officers arrived, the man was out in the building's courtyard, stabbing his wife, sources said.

The police officers ordered him to drop the knife, but he refused, according to sources. Officers fired shots and the man was fatally hit in the chest. He and the woman were taken to a hospital where he was pronounced dead.

The woman remains in critical condition with multiple stab wounds.

The investigation is ongoing.
