Rapper Nelly was left shocked and stunned when police in Texas found drugs on his tour bus on Thursday morning (11Oct12) - because he had no idea a member of his entourage had allegedly smuggled heroin and marijuana aboard.

The rap star and fellow passengers were briefly detained by border cops in Sierra Blanca after a stash of drugs was uncovered during a routine vehicle search.

Brian Keith Jones, an associate of the star, was taken into custody after confessing the drugs were his - and Nelly was allowed to continue his journey.

Speaking to Tmz.com on Thursday afternoon, the Hot in Herre hitmaker said, "It is my understanding a member of my staff made an unfortunate decision to bring unlawful materials onto our tour bus that resulted in his arrest this morning.

"Neither I nor anyone else on the tour bus was aware of his decision to bring these on board. Law enforcement officials did not press charges against anyone other than that individual."
