Could this have been the gun that was in his bag?
The photo, which was posted to the TSA's Instagram account Friday afternoon, included a caption that said it was found at the same airport where the rapper was arrested.
"#TSACatch - This 5.7X28mm pistol was discovered in a carry-on bag today at the #Atlanta Hartsfield-Jackson (#ATL) International Airport," the caption reads. "It was loaded with 29 rounds plus one in the chamber. This could have been legally packed in checked baggage. Learn more about traveling with firearms at TSA.gov."
Waka's mother and rep, Debra Antney, told TMZ that the bag actually belonged to his fiance, and he took it accidentally.
