DENVER -- We have an update on a 7NEWS Investigation reported Monday night concerning missing security badges at Denver International Airport.

The airport recently revalidated all badges issued to airport employees. After the processing of the approximately 23,000 badges, some 3,000 badges were unaccounted for, 7NEWS reported.

City officials said Monday that they didn't know where the badges were, but on Tuesday they released some new information.

Airport security staff members said that they found that 10 percent of those 3,000 badges belong to transient airline flight crews, 20 percent belong to people who simply missed the deadline for revalidation, and 70 percent belong to furloughed employees.

No badges were invalidated because of felony convictions or criminal watch list information, DIA officials said. At no time were any badges considered lost or unaccounted for, they said.

People with invalid badges must now follow federal regulations to apply for a new badge, officials said in a press release.

"Any person attempting to enter a secured area of the airport with a deactivated badge will be stopped at a screening checkpoint. Any person attempting to enter a restricted area of the airport by using the deactivated badge in a card reader will set off an alarm," the DIA press release said.

DIA officials said that they are confident that the deactivated badges pose no security risk to the airport.
