A bus connected to Lil Wayne's "America's Most Wanted" tour was pulled over in Oklahoma around midnight Thursday because its taillights were out. When officers approached the bus, they noticed signs of drug use and demanded to board the bus, TMZ reports.

However, the driver refused to allow the cops entry, locking the door and telling police they had to get a search warrant before he'd unlock the doors.

Lil Wayne and T.I. had left the city on private jets, but it's possible 2 Chainz was on the bus.

Officers eventually towed the bus to a nearby training facility to while they waited for a search warrant. They finally obtained one early Thursday morning, and after boarding the bus they immediately placed several passengers under arrest for "interfering with police process."

Cops tell TMZ they aren't sure if 2 Chainz was on the bus, but say the bus is "connected" to the rapper.
