An Alameda County Sheriff's Office deputy has been arrested in connection to a possible "revenge" beating of an inmate at the Santa Rita Jail in Dublin.
Joseph Bailey, 28 and of Tracy, is accused of facilitating and allowing a small group of inmates to physically assault another inmate in minimum security, according to the Sheriff's Office. The alleged incident occurred on Oct. 24, 2017.
After an investigation, the Alameda County District Attorney reviewed the case and filed criminal charges against Bailey, who has served with the Sheriff's Office since Jan. 5, 2015.
Bailey is charged with felonious assault likely to cause great bodily injury and assault under the color of authority, according to the Sheriff's Office.
"The moment I heard of these allegations, I directed my staff to do a complete and thorough investigation," Alameda County Sheriff Greg Ahern said. "I am confident this single incident is isolated to this individual."
The Sheriff's Office believes Bailey got involved in the jail fight to get back at the victim inmate who got into an argument with him earlier. NBC Bay Area is told the inmate ended up with lacerations, severe bruising and a fractured nose.
Bailey is out on bail and has been placed on paid leave.
