The Federal Bureau of Prisons website Friday showed the rapper at an Atlanta penitentiary with a release date of Sept. 29.
The 30-year-old rapper, whose real name is Clifford Harris, was released from an Arkansas jail Wednesday and made the 375-mile trip to Atlanta in a luxury motor coach.
T.I.'s attorney, Steve Sadow, said Thursday that there was an issue involving the rapper's transportation.
Sadow said Friday there was never any intent to mislead or misstate T.I.'s method of transportation, and he hopes the issue can be cleared up quickly so T.I. can return to the halfway house.
