The federal Transportation Security Administration says 12 security officers at Charlotte Douglas International Airport botched some baggage inspections and should be fired.
The agency said in a Friday news release that the process to remove the 12 from their jobs is under way. None of the security officers is currently on duty at the airport.
Investigators say an internal audit found that in a week last June, about 80 bags of more than 80,000 were improperly screened.
The agency says no security threats were related to the bags.
The same investigation led to the firing or resignation of four workers who had not yet passed probationary periods.
A spokesman for TSA says other security officers have been temporarily sent to Charlotte so that screening operations aren't affected.
