A man was fighting for his life after being shot in the head in East Flatbush Saturday, police said.

The unidentified victim was struck once in front of 2303 Bedford Ave. shortly before 6 p.m., authorities said. The wounded 37-year-old was taken to Kings County Hospital and was not expected to survive the shooting, police said.

The shooter fled the scene in a dark-colored vehicle, authorities said. Radio transmissions described the car as possibly a “blacked-out” Mercedes.

As of late Saturday afternoon, one New Yorker had been killed and another left critically injured in a spate of overnight shootings in the Bronx and Brooklyn that left seven others hurt.
