2 Chainz‘ tour bus was stopped for suspicion of drugs last night in Oklahoma City.

According to TMZ, the police initially pulled the bus over for a broken taillight and noticed signs of drug use on the vehicle. Before entering the bus, the driver locked them out and insisted they obtain a warrant first. After obtaining the warrant, police arrested 11 passengers, including Chainz. They have since released the 35-year-old rapper, but seven of the individuals could be facing misdemeanor charges for interfering with official process.

2 Chainz was arrested earlier this year in June for possession of marijuana. Despite this setback, he is still on schedule to perform at this year’s Video Music Awards.
