T.I. was summoned Thursday by an Atlanta judge to explain why he should not have his probation revoked following his Sept. 1 arrest for possession of a controlled substance.

According to paperwork obtained by E! News, convincing the judge that T.I. should remain free might be a daunting task. In the summons, the 29-year-old's probation officer, Jack D. Briscoe, revealed that L.A. County sheriff deputies also found codeine, ecstasy and marijuana in his possession at the time of the arrest. Adding insult to injury, T.I. tested positive for opiates, and had associated with convicted felon, Cortez Thomas, who had not been approved by his probation officer. This latest legal debacle comes just months after Tip's release from federal prison stemming from a weapons possession charge in 2008.

"We are very disappointed in Mr. Harris' recent conduct," U.S. Attorney Sally Quillian Yates told E! News. "We will make our sentencing recommendation at the revocation hearing."

As previously reported Tip and his wife Tameka "Tiny" Cottle were pulled over in West Hollywood earlier this month after making an illegal U-turn on the famed Sunset Boulevard. Upon further review, authorities reportedly smelled marijuana prompting them to search the vehicle and later uncovered what ecstasy pills.

At press time the Grammy winner's lawyer declined a request for an interview. No official date has been set for T.I. to appear in court.
