DANVILLE, Va. – Danville Police have heightened security at George Washington High School following reports of a social media threat.

Danville Police were notified of the threat about 8:15 a.m. Friday and are assisting Danville Public Schools employees with security on campus. The school was placed on a lockout Friday morning because of the threat.

“All students are safely in class at this time,” police wrote in a news release. “After completing searches, no evidence has been identified to validate this potential threat that originated via social media.”

Students were dismissed from buses one-by-one Friday morning, with security checks as each entered the building. Nothing unusual was found and police are working now to identify the source of the threat.

The school system said, “For the remainder of the semester as we continue to investigate, we will continue security checks, and we discourage students from bringing bookbags, unless they are clear, to expedite entry into school each day. We will communicate when that investigation concludes. Again, these are safety precautions we are taking to make sure that our school remains safe for students to learn.”
