The Placer County Sheriffs Office was served with a federal subpoena earlier this month, a department spokeswoman confirmed Friday.
The agency declined to disclose the contents of the subpoena, served the first week of August, because of legal constraints.
The subpoena specifically states that this office is not allowed to discuss this matter with anyone, the department said in a statement.
Dena Erwin, a department spokeswoman, said the federal subpoena had nothing to do with other employee probes.
In July, a decorated Placer County sheriffs deputy, Ken Skogen, was arrested on suspicion of having a sexual relationship in 2011 with a 17-year-old girl who was a volunteer at the time with the Sheriffs Office.
The department said in its statement Friday that we take all allegations against our employees seriously but these allegations must be kept confidential, according to state law. If criminal conduct is found during an internal investigation, we have and will continue to promptly forward the case to the Placer County District Attorneys Office for further investigation and possible prosecution.
