OCEANSIDE -- A city police officer was injured when he put his arm through a window while struggling with a suspect Friday, an Oceanside Police Department spokesman said.

The officer was called to the 400 block of Grant Street about 1 p.m. to investigate a report that a man was drinking alcohol in a parked car, Sgt. Kelan Poorman said. When the officer tried to talk to the suspect, the man ran, Poorman said. After a short chase, the officer tackled the suspect on Garfield Street, Poorman said.

The officer's arm crashed through a building window during the struggle, and he suffered deep cuts to the arm, Poorman said. He was taken by helicopter to Scripps Memorial Hospital in La Jolla, where he was expected to recover.

Backup units responded to Garfield Street and arrested Oceanside resident Jorge Medina, 34, on suspicion of resisting arrest, Poorman said.
