A city man is facing two felonies after he injured a police officer with his dirt bike, Albany police said.

Two officers were stopped about 6 p.m. Saturday near North Manning Boulevard and Livingston Avenue when they saw a group of dirt bike riders who were on the road illegally. One of the bikes stalled near the intersection. As one of the officers got out of the police car, Jahquell Griffen, 21, managed to restart his bike, police said.
