This week's roundup was one of the largest involving Transportation Security Administration employees this year, the New Orleans Times-Picayune reported Wednesday.
The investigation at Louis Armstrong International Airport began after a TSA employee reported witnessing the thefts and saw screeners divide up the spoils, sheriff's records state.
Andrea McCauley, a TSA spokeswoman, said the screeners have been suspended pending the outcome of the criminal cases.
"The investigation is ongoing. TSA has a zero-tolerance policy for any criminal activity," she said.
Arrests of airport screeners are unusual, but there have been others within the past six months in Denver, Detroit, and Indianapolis, the Times-Picayune reported.
