Three guards were injured by an inmate at a jail in Corner Brook on Monday.
The corrections officers were trying to move the 50-year-old man from one cell to another, but he refused to go quietly.
It's alleged he became irate and violent, biting two guards and trying to injure the other's leg.
One of the officers was taken to hospital to be checked out.
According to a Royal Newfoundland Constabulary news release, the Massey Drive man was already being moved to another cell "for disciplinary reasons," but the release did not elaborate.
He was due in court Tuesday, charged with three counts each of assaulting peace officers and disobeying court orders.
