Two data storage devices containing classified information are missing from Los Alamos National Laboratory, officials said.
Lab spokesman Kevin Roark refused to say whether the information could jeopardize national security. He said the "Classified Removable Electronic Media" were discovered missing from the Weapons Physics Directorate during an inventory check Wednesday. He refused to specify exactly what was missing but said the items could be products such as CDs or floppy disks.
A search was under way, and lab Director Peter Nanos said he would order a full inquiry into what happened.
This is the second such incident in recent months. Classified electronic media was also reported missing in May. That data had been set to be destroyed before it went missing, Roark said at the time.
