BOSTON (AP) — The Transportation Security Administration says it has moved to fire six bag-screeners at Boston’s Logan Airport who performed inadequate luggage checks because they were distracted by their cellphones or other electronic devices.

The agency says 14 others face suspension for inattention to duty.

The moves were prompted by a routine audit that showed some officers weren’t paying close attention to monitors that display the contents of each bag screened by an explosives detection machine. Others ignored protocols to hand-inspect bags that triggered alarms.

The TSA tells The Boston Globe that no dangerous materials got through the detection system as a result.

The 20 employees facing dismissal or suspension include two managers and a supervisor and worked in the same baggage room. They have seven days to appeal.
