He’s already been sentenced to 11 months in prison for violating his probation, but T.I. won’t be charged for the incident that put him there.

The D.A. has decided not to go ahead with the case because T.I. is already having to serve the time no matter what -- the arrest itself was the violation.

T.I. spent a year in prison on a federal weapons charge just last year, and was not even half way through a three-year probation term when he was slapped with this latest sentence.

No word if the charges against T.I.'s wife Tameka, who was a passenger in the car at the time of the arrest, will also be dropped.
