Police at a Georgia university say a security officer stabbed seven times in knife attacks on the campus has been released from a hospital.

Former student Joseph Anthony Scott faces charges including murder in the May 3 killing of 19-year-old freshman Donnell Phelps at Fort Valley State University in central Georgia.

Police say Scott was harassing and groping three young women near the school cafeteria Tuesday and Phelps came to their aid by trying to intervene. They say Scott pulled out a pocket knife and stabbed Phelps to death.

Police say Scott then stabbed security officer Ernest Johnson as he left the campus.

Campus Safety Police Chief Kenneth Morgan said Johnson has returned home from the hospital, but will need additional time to recover from his injuries.
