CHARLOTTE, N.C. -- Transportation Security Administration says it stopped three travelers suspected of bringing loaded guns from boarding planes at Charlotte Douglas International Airport Friday morning.

TSA says the first incident occurred just around 6:30 a.m. at Checkpoint D, the second at Checkpoint B just after 10 a.m. and the third reported around 9 a.m. The three incidents are not believed to be related, TSA says.

Charlotte-Mecklenburg Police identified one of the suspected travelers as Shane Michael Derry, 33, of Lexington. Derry was charged with a misdemeanor possession of firearm on city property, according to CMPD.

Derry is issued a $1,000 secured bond.

TSA says officers have detected 12 firearms at CLT checkpoints this year. Last year, TSA found 53 firearms.

TSA said the legal method of traveling with a firearm is to bring it as checked baggage, have the firearms unloaded, packed in a hard-side case, locked and packed separately from ammunition. Then the firearm must be taken to the airline check-in counter.
