Holtzclaw, a 27-year-old Enid, Oklahoma, native who attended EMU from 2005 to 2008 on a football scholarship, is being held in the Oklahoma County Jail on $5 million bond.

The arrest warrant -- authorized by a judge shortly before the arrest was made -- alleges that Holtzclaw was wanted for first-degree rape, rape by instrumentation, three counts of forcible oral sodomy, two counts of sexual battery and two counts of indecent exposure.

Charges are expected to be filed Friday, Aug. 29, and police said he could face life in prison without the possibility of parole if he's convicted.

"We received a complaint and also uncovered a number of other individuals, females, that had experienced the same thing with this officer," Oklahoma City Chief of Police Bill Citty said during a Thursday evening press conference.

"All his victims were black females and they range in the ages of 34 to 58. Right now I've identified seven (women), six of whom we've received statements from and one we're still attempting to get statements from. So you have seven total over a period of five or six months."

Citty said Holtzclaw had been working with the OCPD for three years, most recently in northeast Oklahoma City, and that all of the incidents occurred during his 4 p.m. to 2 a.m. shift. while he was on duty.

"The types of acts committed were anywhere from just requiring the females expose themselves, to fondling the females, and...actual intercourse," Citty said.

"About three of the victims were asked or required to perform oral sodomy on this officer."

Oklahoma County District Attorney David Prater said he expects more women to come forward since all of the allegations only go back a few months and Holtzclaw has been on the force since 2011.

"We kind of anticipate there may be more victims out there because this goes back to February," Prater said.

"February is the earliest that we have here.... If there's anyone that was victimized by this officer, we certainly want to hear from you."

According to a report from The Oklahoman, earlier this year Holtzclaw was one of four officers named in a wrongful-death lawsuit stemming from the May 1, 2013, death of Clifton Armstrong.

Oklahoma's medical examiner ruled the death an accident and Prater cleared the officers of any wrong-doing in the matter.

As a four-year starter at Eastern Michigan from 2005-2008, Holtzclaw holds the EMU record for most career starts (47) and is second all-time in school history in tackles (437). He earned Freshman All-American honors from the Football Writers of America after his first season in Ypsilanti.
