Naval Base Guam issued a shelter-in-place order Wednesday afternoon after the installation received a bomb threat. The order was lifted approximately three hours later.

The bomb threat was issued around 12:15 p.m. local time. Security personnel, emergency responders and Navy Explosive Ordnance Disposal Mobile units responded to the scene, the base said in a series of posts to its official Facebook page.

The shelter-in-place order remained in effect until 3:05 p.m., when the base issued an “all clear” update to its posts.

“An investigation continues at Barracks 1, 2, and 3,” the base said in the post. “[Naval Base Guam] employees, residents and patrons are to remain clear of these buildings and nearby areas.”

Traffic at the base’s main gate and back gates, which were previously closed to inbound traffic, reopened at 3:05 p.m. as well.

Parents were advised that school pick-ups at Cmdr. William C. McCool Elementary and Middle School would be delayed, although no additional information was available. 

Spokespeople for Naval Base Guam and Joint Region Marianas did not immediately respond to email requests for comment as of Wednesday afternoon.
