Prince William County, Va. – The call that prompted a double bomb threat to Prince William County’s courthouse Tuesday originated from Woodbridge, sources say.

Police by 3 p.m. had closed several streets around the judicial center that serves Prince William, Manassas, and Manassas Park and had evacuated everyone inside. Officials closed the courthouse for the remainder of the day, and bomb sniffing dogs were used to check the premises as well as any cars leaving courthouse, according to reports.

Just before 4 p.m., there had been no reports of any bombs found and no injuries.

It all started just before 2 p.m., when sources say a male called in a bomb threat to the complex from a pay phone at a Citgo station on U.S. 1 in Woodbridge. The caller told authorities one bomb inside the courthouse would explode at 2 p.m. and the second exactly one hour later, sources say.
