A Fairfax County police sergeant was arrested Saturday in Virginia on charges of aggravated sexual battery, the department said.

Police identified the sergeant in a release as Matthew Sylvester, of Warrenton. He was arrested around 1 a.m. by the Fauquier County Sheriff’s Office on two counts of aggravated sexual battery.

The charges stem from an off-duty incident involving two individuals who were known to Sylvester, according to the Fairfax County Police Department.

Sylvester, 40, is a 16-year police veteran who works in the Internal Affairs Bureau.

Additional details regarding the arrest were not immediately made available by police.

Sylvester is on administrative leave pending the investigation.
