OKLAHOMA CITY - News 9 has learned rapper 2 Chainz was among 11 people arrested Thursday after his tour bus was pulled over in Oklahoma City for a traffic violation that led to a showdown with police.

The rapper performed Wednesday night with Lil Wayne and T.I. at a concert at Chesapeake Energy Arena. Just after midnight Thursday, police pulled over the tour bus at Interstate 40 and Meridian for a broken taillight. 

The officer suspected there were illegal drugs on the bus, but the driver locked the doors and refused to let police inside. Everyone on board also refused to leave the bus.

Police had the tour bus towed, with the people still on board, to the police training facility at 850 N. Portland until officers obtained a warrant to search the bus.

Several hours later, the people on board the bus who initially refused to open the doors were taken off the vehicle and arrested. All 11 were booked into the Oklahoma County jail for a state misdemeanor charge of obstruction.

Officers searched the vehicle. Police have not said what they found during the search.

The rapper is best known for the songs "We Own It," "Birthday Song" with Kanye West, and "No Lie" featuring Drake. He also had a guest appearance on the CBS sitcom, Two Broke Girls.
