WINSTON-SALEM, North Carolina A university in Greensboro, North Carolina, lifted a campus-wide lockdown alert issued on Friday after reports that a man carrying a rifle was seen near a classroom building.
No shots had been fired and no one was injured, North Carolina A&T State University, said. It said on its website that normal activities could resume on the campus.
School officials did not immediately return a call seeking comment about whether a gunman had been found.
Several public schools in Greensboro were also locked down Friday due to their proximity to the university.
Educators and police around the United States remain on high alert for possible shooting incidents in the wake of an attack on an elementary school in Newtown, Connecticut, in December that left 26 dead, including 20 young children.
Last week the University of Rhode Island was locked down for a few hours after reports of a possible gunman. That incident ended with no gunman found, police said.
North Carolina A&T State University has more than 10,000 students.
