ATLANTA (AP) — Police say a member of the rap group Travis Porter was arrested when he tried to go through a security checkpoint at the Atlanta airport with a loaded gun.

Atlanta police say 21-year-old Harold Duncan Jr. had a Glock .45 caliber handgun in his carry-on luggage. Screeners discovered the gun around 8 a.m. Wednesday.

Duncan was jailed without bond, and is scheduled to appear in court on Thursday. The jail website says Duncan is charged with carrying a weapon in an unauthorized location.

It was not immediately clear whether he had a lawyer. A media contact listed on the group’s website did not immediately respond to an email Wednesday evening. The group’s hits include “Go Shorty Go.”

The TSA says passengers can transport unloaded guns in a proper carrying case in checked luggage, but firearms are prohibited in carry-on bags.
