University of South Carolina students were told to shelter in place Sunday after an unconfirmed report of an active shooter on the main campus.

The two incidents occurred just days after there were shooting scares at both Villanova and the University of Tennessee at Chattanooga on Aug. 21.

There is no evidence of a shooter at the University of South Carolina’s campus library, a school spokesperson said Sunday, after a schoolwide alert about a shooter who had been reported to be on the Columbia campus.
