An Alexandria Sheriff's Office deputy accused of sexually assaulting a female inmate has been fired.

According to a news release, an inmate at the William G. Truesdale Adult Detention Center told another deputy that Deputy Bryant Pegues sexually assaulted her Tuesday morning.

"She did not hesitate ... [to tell another] deputy,who immediately reported it and did the right thing," Sheriff Dana Lawhorne said.

Sheriff's Office commanders contected Alexandria Police, and Pegues, 52, was arrested later that evening.

He is charged with rape and carnal knowledge of an inmate. He was denied bond.

"We are entrusted with the lives and safety of those in our custody," Lawhorne said. "The criminal actions of Bryant Pegues are a grave violation of the public trust. We will continue to assist Alexandria police and the Commonwealth’s Attorney as they pursue a successful prosecution."

Alexandria Police are withholding Pegues' mugshot, adding releasing it could hurt the ongoing investigation.

Sheriff Lawhorne said there may be more victims.

"If he's done it before, and there's more than one [victim], let the chips fall where they may and it'll fall right on him," Lawhorne said.

Pegues, a resident of Oxon Hill, Maryland, has lost his job with the sheriff's office. He joined the department in 2007.
