A Rochester man is facing charges, after a robbery and chase.
Police say the 18-year-old was part of a group that pulled a teen into a stolen car at Lake Avenue and Spencer Street and beat him, before stealing a cellphone.
Police stopped the car with spike strips on South Plymouth Avenue, and police nabbed the unnamed suspect after a brief foot chase.
He's charged with robbery and grand larceny.
Two cruisers collided during the chase -- two officers were taken to the hospital to be checked out.
