NEW YORK, June 21 (Xinhua) -- Authorities have lifted a lockdown at the Naval Air Engineering Center in Lakehurst, New Jersey, local media reported Monday.
The lockdown, which lasted for about two hours Monday morning, was prompted by "several incidents," according to David Carbajal, a spokesman at the base.
Authorities provided no details about the incidents, but CBS television, citing sources, said two separate incidents occurred, one involving a delivery truck driver found to have a shotgun with him.
A second incident allegedly occurred at a non-commercial gate, but there was no word on what happened at that gate, CBS said.
The base is known as the place where the airship Hindenberg exploded in 1937. One of its main missions is to deal with equipment used to launch aircraft from aircraft carriers, reports said.
