"We stopped the bus about midnight and it was near I-40 and Meridian," Oklahoma City Police Department Sergeant Jennifer Wardlow told Radio.com while the investigation was still underway. "The reason for traffic stop was it looks like there was a broken taillight. When officers went up to bus and made contact with the driver, there was evidence of drug usage going on the bus. We're not getting into specifics of what it was, but it was apparent to the officers that there was drug use going on the bus. The driver was taken into custody without any problem. When he got out and shut the door, it locked so the officers couldn't get into the tour bus.

"The decision was made to tow the bus to our police training facility and obtain a warrant. It was about 8 a.m. Oklahoma time when they were able to get a warrant, and it was at that time that all the people who were on the bus came off."
