A former sergeant in the Fairfax County sheriff’s office has been charged with assault and battery of a person he detained and brought to the county jail, the sheriff’s office said Tuesday as it released video that shows the man forcing a handcuffed suspect into the back of a squad car and repeatedly punching him in the face.

A former Fairfax County Sheriff’s deputy is facing assault charges after video shows he punched a handcuffed man who was being arrested on Sept. 11.

For the second time in months, a Fairfax County sheriff's deputy has been fired for allegedly assaulting a person in custody. The most recent incident happened earlier this month. Sgt. Joshua Silver was charged with assault and battery after he was seen on camera appearing to punch a handcuffed man repeatedly inside a marked cruiser.
