Rock star Rick Derringer was detained at Hartsfield-Jackson International Airport for having a loaded gun in his carry-on bag in a secure area, according to officials.
The Grammy-winning "Rock & Roll Hoochie Koo" singer was on his way back to the United States from Mexico on Monday night when TSA agents found the gun, Channel 2 Action News reported.
Federal law bans weapons on planes or in carry-on luggage.
Derringer, 69, was heading to a connecting flight to Florida, where he has a valid concealed weapons license, when a TSA supervisor noticed a gun magazine in the X-ray of his bag. The agent found a Kel-Tec .380 handgun and 12 rounds, Channel 2 reported.
The FBI has taken over the investigation.
