Pearl Harbor all clear after 'incident'

·1-min read

The US military has given the "all-clear" after an unspecified threat prompted an hours-long lockdown of Joint Base Pearl Harbor-Hickam.

A military news release didn't elaborate on the "potential incident" that required the base to close entrances to the base and to direct residents and employees to shelter in place at 9.39am on Tuesday.

"While the base remained fully operational, the Emergency Operations Center was manned to coordinate the response to the threat," said an afternoon release announcing the all-clear.

Units from the Honolulu Police Department and Federal Fire Department helped with the investigation, the military said.

During the investigation, tours were suspended while guests at the USS Arizona Memorial and the Pearl Harbor Aviation Museum sheltered in place.

Tours were later allowed to resume.
