(NECN) - Four inmates have now been indicted in the stabbing of a correction at Souza-Baranowski Correction Center in Shirley, Mass.
Officer Nathan Beauvais was stabbed in the neck with a prison made knife in June at the maximum-security prison.
He has since recovered.
A melee followed the stabbing and six other correction officers were injured.
On Wednesday, a grand jury indicted four inmates on various charges, including armed assault with intent to murder.
