(STMW) -- One person was arrested after a Chicago Police officer was hit by a stolen van Thursday afternoon in the West Englewood neighborhood on the South Side.

The officer was standing with others trying to curb the stolen van about 2:30 p.m. in the 6000 block of South Winchester when the driver--a male--rammed the van into a squad car, police said. The van then struck a 26-year-old officer, police said.

The officer is being treated at Little Company of Mary Hospital for a leg injury, police said. He may also have a concussion.

One person was in custody, and police are looking for a second offender, police said.
