“He remains subject to a criminal investigation being conducted by the Oakland Police Department,” according to the statement.

Perez had been implicated in the investigation after an announcement on June 13.

Contra Costa County Sheriff’s Office spokesman Jimmy Lee told CBS San Francisco “We are aware of the allegation against our employee and are awaiting the criminal investigation interview by Oakland PD. We will be conducting our own administrative investigation immediately.”

Perez had been placed on administrative leave after coming under investigation.

The internal investigation into the sex scandal has shaken the Oakland Police Department, leading to the June 10th resignation of Police Chief Sean Whent and a rapid series of leadership changes ordered by Oakland Mayor Libby Schaaf.

At least two of the five Oakland police officers placed on administrative leave following allegations of sex with a minor have resigned from the Oakland Police Department.

The woman believed to have been at the center of the sex scandal, and underage for at least part of that time, goes by the name Celeste Guap.

She told CBS San Francisco, on June 10th outside the Oakland Police Department, that she had sex with 14 officers from the Oakland Police Department, as well as five from the Richmond Police Department, three Alameda County Sheriff’s deputies and a Livermore cop. She says that while she was underage she only had sex with three officers — all from Oakland PD.

In the statement released Thursday, Contra Costa County Sheriff David Livingston was quoted as saying, “We earn the public trust through honesty, trans-parency and accountability. Although this case involved one deputy out of the over one thousand Sheriff’s Office employees, we will not tolerate even a single breach of the public trust we work so hard to earn.”
