OKLAHOMA CITY (WWJ) — An Oklahoma City police officer who played college football at Eastern Michigan is facing new charges of sexually assaulting women while on the job.

Prosecutors have filed ten new charges against 27 year-old Daniel Holtzclaw, including first-degree rape, forcible oral sodomy and indecent exposure. He was arrested in August and charged with 16 crimes at that time.

Holtzclaw played football at Eastern Michigan in the mid-2000s and was considered talented enough to be given a tryout with the Detroit Lions, though he didn’t make the team. He then moved to Oklahoma. Holtzclaw has pleaded not guilty to all charges and is free on bond.

Holtclaw’s defense attorney, R. Scott Adams, has said his client was shocked and devastated by the allegations and denies them.

The investigation began when police said a woman complained that Holtzclaw had sexually assaulted her during a traffic stop on a boulevard about two miles north of the state Capitol.

The police department placed Holtzclaw on leave shortly after the allegations emerged in June, Chief Bill Citty said when announcing the arrests.

“We started the investigation and we started looking at traffic stops he had made throughout the previous months to try to identify and initiate contact with females that we knew he had stopped during that period of time … to see if they had been sexually assaulted,” Citty said.
