Three of the officers involved in a fatal beating of Robert Brooks, a handcuffed inmate at the Marcy Correctional Facility upstate New York, were previously accused of abuse and assault, according to court documents obtained by CNN.

The state prison inmate died Dec. 10 after being beaten by correction officers at Marcy Correctional Facility in Oneida County.

Robert Brooks died following a brutal attack at a New York state prison earlier this month, with the incident captured on multiple officers' body cameras.
