WEAPONS FOUND ON RAPPER 2 CHAINZ TOUR BUS.

Police in Oklahoma City discovered two semi-automatic pistols and a 12-gauge pump shotgun along with some prescription painkillers and marijuana residue on a tour bus occupied by rapper 2 Chainz and 10 other men, according to court documents. The men were arrested on August 22 after refusing to get off the bus following a traffic stop. The 35-year-old rapper, whose real name is Tauheed Epps, had performed with Lil Wayne and T.I. in Oklahoma City the night before.
2 Chainz and the others were charged with obstructing a police officer. All were released after paying $US2,000 ($A2,236) bail.

Local newspaper The Oklahoman reports police who searched the bus found two .40-calibre semi-automatic pistols and a partial box of ammunition for them, according to the documents. Twenty shells for the 12-gauge shotgun also were seized.

Police found the prescription medications hydrocodone and Flexeril but without prescriptions, according to the search warrant return. Officers also reported discovering marijuana residue along with metal grinders and smoking papers with marijuana residue.

An affidavit filed last week says an officer pulled over the bus on Interstate 40 because its rear taillights weren't working.

The officer smelled marijuana when the driver opened the door, the affidavit says, and the officer "could actually see smoke inside the bus around the door."

The affidavit also says a passenger on the bus, Abdullah Mujahid, shook his head "no" when he was ordered to get off and held up a small copy of the US Constitution.

The Atlanta-based rapper, initially known as Tity Boi, was a member of the rap duo Playaz Circle before going solo. His 2012 debut album, Based on a T.R.U. Story, topped the Billboard charts. His new album, B.O.A.T.S. II: Me Time, is set to be released.

He has also collaborated with many big stars, including R. Kelly, Drake and features on Jason DeRulo's current hit Talk Dirty.
