The bus was pulled over at a border patrol checkpoint in Sierra Blanca, when a police dog detected the presence of drugs on the bus, according to law enforcement sources.
Along with Nelly there were six other passengers on the bus, all of whom were detained during the search. Brian Keith Jones, one of the passengers, told police the drugs and gun were his and was placed under arrest. Nelly and the five others were then released.
There's been no word from Nelly or his camp regarding the incident.
