A captain with the Franklin County Sheriff’s Office has been placed on administrative leave while Vermont State Police investigate allegations that he assaulted a man in custody.

The sheriff’s shared surveillance footage that shows the suspect sitting on a bench with his legs chained with shackles. The suspect is then seen attempting to leave the bench while two officers ask the man to remain seated. When the suspect refused, the video appears to show Capt. John Grismore kicking the standing suspect in the groin, forcing him to sit.

In a press release, the Sheriff’s Office said its command staff was notified Sunday of the alleged assault by patrol deputies. Sheriff Roger Langevin placed Grismore on administrative leave, and referred the matter to the Franklin County State’s Attorney’s Office, which requested a criminal investigation by Vermont State Police.
