NEWPORT NEWS, Va. — About an hour after Christopher Newport University (CNU) issued an alert Wednesday morning after someone was spotted walking with a gun on campus, the university gave the “all clear.”

All clear. No known continuing threat to campus. Class begin at 9 a.m. — Christopher Newport (@CNUcaptains) February 11, 2015

CNU informed students classes would begin at 9 a.m.

Earlier Wednesday, the university ordered students and staff to stay indoors after two people spotted a man with a gun walking on the Newport News campus.

We have received two reports of an unknown individual holding a handgun while walking across campus. The individual is described as a black male, 5 foot 8 inches wearing a tan jacket and a knit cap. Campus Police and Newport News Police have not been able to locate this person. All CNU students, faculty and staff should remain in their building until further notice.

CNU is located on a 260-acre campus in Newport News, Virginia. About 5,000 students attend the university.
