Authorities said 2 Chainz bus was pulled over for a broken tail light when officers "noticed there was evidence of drug usage.”
When most of the men on the bus refused to leave the vehicle and locked themselves in, officers had it towed to a police training center with everyone still on board. After obtaining a search warrant, the men were arrested and charged with "interfering with the police process."
Law enforcement sources told TMZ that drugs were found on the bus, though they weren't specific about the variety.
2 Chainz, who allegedly tried to check marijuana onto a flight in June, tweeted about the incident on Thursday.
"Don't ask me ask OKC police department what they found on the bus,,,,u won't get an answer because nuthn was found," he wrote.
"This sh** will make u go crazy," he added. "Our bus gets pulled 1 a week and they always say I smell weed I need to search ur bus. Sht gets tiring."
