Tauheed Epps, better known as rapper 2 Chainz, and 10 other men on his tour bus were arrested by Oklahoma City police Thursday morning after they refused to leave the bus following a traffic stop, authorities said.

All 11 were arrested on misdemeanor complaints of obstruction, police Sgt. Jennifer Wardlow said. The artist appeared Wednesday night at the Chesapeake Energy Arena with Lil Wayne.

Police said officers with a drug interdiction task force stopped the bus about midnight on Interstate 40 near Meridian Avenue because of a broken taillight. While questioning the driver, police found evidence of drug use.

The driver got off the bus, but the door closed and locked behind him. Wardlow said the rest of the men on the bus refused to exit.
