A search prompted by a bomb threat at a U.S. Army base in Utah has ended with an FBI spokeswoman saying agents have not turned up anything suspicious.
FBI spokeswoman Debbie Dujanovic Bertram says the search with bomb-sniffing dogs ended late Monday, about six hours after the threat halted construction of a National Security Agency data center at Camp Williams and the site was evacuated.
Construction will resume Tuesday.
The FBI says it isn't concluding that the bomb threat was a hoax, only that agents found nothing.
The NSA broke ground on the $1.2 billion cyber security center in January.
Camp Williams is about 25 miles south of Salt Lake City.
