Nellis Air Force base shuts entrance after threat

LAS VEGAS (AP) - Military officials say the main entrance of an Air Force base outside Las Vegas was shut down after a man made a verbal threat to a guard at the gate.

Nellis Air Force Base spokesman Chuck Ramey said the entrance was closed more than three hours on Friday and federal agents arrested the man, who was a civilian.

Ramey said the threat was made at about 3 p.m. and was believed to be an isolated incident. He said operations at the base - including other entrances - were not affected.
