2 Chainz has been arrested following a police standoff in Oklahoma on Wednesday night.

According to TMZ, the rapper’s tour bus was pulled over in Oklahoma City around midnight after police noticed its tail lights were out. Upon approaching the vehicle, police noticed signs of drug use and attempted to board the bus.

However, the bus driver would not allow them to enter, insisting they obtain a warrant first.

After returning with a warrant, cops eventually entered the bus hours later, where they arrested 11 passengers including 2 Chainz for “interfering with the police process.”

It’s unknown if police found drugs or whether additional charges will be filed.

2 Chainz is currently on tour with Lil Wayne and T.I., and is scheduled to appear at Sunday’s MTV Video Music Awards in Brooklyn.

UPDATE: 2 Chainz has returned to Twitter to address the situation.

“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 said. “This shit will make u go crazy , our bus gets pulled 1 a week and they always say I smell weed I need to search ur bus. Sht gets tiring.”
