Rapper Clifford “T. I.” Harris had a contradictory Saturday to say the least, as he was arrested for illegal weapons possession just hours before a scheduled performance at the BET Hip-Hop Awards – where he won two awards.

The 27-year-old Clifford Harris, better known professionally as T. I., was arrested Saturday in an Atlanta, Georgia parking lot in what HipHopDX calls a “gun-purchasing transaction.”

T. I. was arrested Saturday afternoon in Atlanta by agents from the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), as he arrived to receive three unregistered machine guns and two silencers his bodyguard had previously acquired for him.

David E. Nahmias, U.S. Attorney for the Northern District of Georgia, said in a statement: “This convicted felon allegedly was trying to add several machine guns to an already large and entirely illegal arsenal of guns.”

“Thanks to the good and quick work of ATF, he is now in custody and his firearms have been seized,” Nahmias added, as quoted by Reuters.

T. I. has a history of illegal activity and was convicted of a violation of the Georgia Controlled Substances Act in 1998 and given seven years probation, the Department of Justice said.

It is illegal for convicted felons to have someone else purchase firearms on their behalf. T. I. had allegedly given his bodyguard $12,000 for that exact purpose. The man attempted to purchase the firearms from an undercover ATF agent without registering them.

He was arrested on Wednesday and agreed to cooperate and help agents find T. I. A search of the rapper’s car and house concluded with more guns being found - three in his car and six in a bedroom closet.

T. I. is scheduled to appear in court Monday, reports Reuters. He has been charged with possession of unregistered machine guns and silencers, as well as possession of firearms by a convicted felon.

The rapper was nominated in nine categories for Saturday’s BET Awards and won two trophies, for Best CD of the Year, a tie with Common, and Best Ringtone for “Big Things Poppin’.”

The rapper’s attorney, Dwight Thomas, told the New York Daily News that he hopes T. I.’s music is more important to fans than his brushes with the law. “When this is all over, we can clear T.I.'s name and he can go back to making the wonderful music he is known for. He's confident in the American legal system and that it will work in his favor.”
