Two Patuxent Institution inmates were arrested in a stabbing yesterday at the prison that left another prisoner in serious condition, a state corrections official said.

Warren James Courts, 20, formerly of the 3800 block of Cottage Ave. in Baltimore, was stabbed in the neck with a homemade knife, said Leonard A. Sipes Jr., a spokesman for the Maryland Department of Public Safety and Correctional Services. Courts was in serious but stable condition last night at Maryland Shock Trauma Center.

Sipes said Courts was stabbed in an area outside a prison housing unit. Two inmates were arrested, but Sipes did not reveal their names because they had not been charged.
