DELAWARE COUNTY, Pa. (CBS) – A former Darby Township police officer is facing some serious charges.

Kevin Joseph Walker is behind bars after Delaware County prosecutors filed rape, sexual assault and other criminal charges against the former officer.

According to the criminal complaint, Walker used his authority as a Darby Township police officer to coerce women into performing sex and sexual acts. The women accuse Walker of harassing and stalking them and say Walker committed some of the crimes while he was on duty and in uniform.

Walker is currently an elected state constable for the City of Chester. He was suspended with the intent to terminate this past July and is currently suspended without pay, pending the outcome of the charges.

Walker was arraigned Thursday afternoon and is now free on bail. He will be required to stay away from the victims.

Walker’s wife turned in his personal weapons and he is required to turn in his badge, gun and other police materials by Friday.
