Three police officers were injured in two separate incidents within an hour of each other in Harlem early Friday, officials said.

An officer suffered an injury at 40 West 115th St. at around 12:30 a.m. and was transported to St. Luke’s Hospital with back pain, according to fire officials.

About a half-hour later, a police cruiser crashed while driving northbound on Lenox Avenue near 116th Street. Two officers were sent to St Luke’s with minor injuries.
