An officer at Maury Correctional Institution in Hookerton is facing multiple drug charges after his arrest this weekend.
Greene County deputies say Edwin Edwards of Greenville is charged with possession of a controlled substance on prison premises, possessing drug paraphernalia, and providing tobacco to an inmate.
The 29-year-old Edwards was arrested Sunday night and his bond was set at $10,000 secured.
A sheriff's report says they seized about 1.3 ounces of marijuana from Edwards. The Department of Correction says officers found marijuana on Edwards and in his lunch bag.
Edwards, who had worked at Maury since June 2008, resigned on Monday.
The DOC says it happened during an unannounced drug interdiction at the prison. A spokesman says these are performed to keep drugs out of the prisons. All visitors, staff and vehicles entering the prison property are searched, with local law enforcement officers present.
