CHICAGO (CBS) –A Chicago Police Officer is in the hospital after he was attacked with a baseball bat. That officer was trying to break up a fight when he was hit in the head.

Members of the Chicago Police Department tell CBS 2’s Courtney Gousman their fellow officer is now in serious, but stable condition at Stroger Hospital.

Police say the male officer was attacked after responding to a battery in progress in the 5700 block of Winchester in the city’s West Englewood neighborhood.

Officers confirm a bat was used and say the officer was hit at least once in the head. Everything took place around 12:40 Saturday morning.

At least a dozen officers responded to the scene to help with the investigation. The person responsible for the attack ran from the scene and no one is in custody.

Police are not revealing the identity of the officer or how long he’s been on the force.

“You’ve got an officer in a one-man car in midnights in Englewood. He responds to a disturbance in the street calls for help, there is a fight in progress and he sees a female being attacked by an individual with a baseball bat. He goes to get out of the car and gets hit before he can do anything. Fortunately, help was just behind him,” said Fraternal Order of Police Spokesman Pat Camden.

About two hours before the bat incident, a police officer was shot at in the Chicago Lawn district. The officer was driving an unmarked police vehicle on the 6600 block of S. Oakley Avenue. The officer was not hurt and no arrest has been made.
