A Secret Service officer assigned to Vice President Joe Biden’s residence was arrested Monday for allegedly sexually assaulting a 14-year-old girl in his custody.

Hector Reynaldo Cuellar of Woodbridge, Va., was charged with three counts of aggravated sexual battery and three counts of taking indecent liberties with a child by a custodian, according to a daily incident report released by the Prince William County Police Department. He is being held without bond.

“The investigation revealed that the 14-year-old female victim was sexually assaulted by the accused family member on separate occasions between August and October of 2012,” according to the Prince William County Police Department’s daily incident report.

There is no mention of his employment with the Secret Service in the police report, but sources told FoxNews.com that Cuellar, 51, is a uniformed division officer assigned to the vice president’s residence in Washington, D.C.

In response to FoxNews.com’s request for comment, Secret Service spokesman Ed Donovan said via email:

“We are aware of the arrest of this employee. He has been placed on administrative leave pending the outcome of judicial action. Any other questions should be referred to the Prince William County police.”

When asked how long Cuellar has been with the Secret Service, Donovan told FoxNews.com, "We aren't providing any further information at this point."

Sources also said that on Tuesday afternoon, the Secret Service’s Security Clearance Division sent around a “Do Not Admit” email notification throughout the agency for Hector Cuellar.

Police were first notified on Sunday, according to the police incident report.

“On October 21st, detectives from the Special Victim Unit received a report of a sexual assault, reported to have occurred in the Woodbridge area of Prince William County,” the report says.

Cuellar was arrested the next day following a police investigation.
