US rapper Snoop Dogg could face drug charges after police said that they found marijuana on his tour bus.

CNN reports that border police checked his bus in Texas after smelling marijuana in a routine check, before finding the drug in some prescription bottles and two other containers.

A Texas police sheriff said in a statement that the rapper "freely admitted" that the drug belonged to him. The statement read:

"During a routine check of U.S. citizenship the inspecting Border Patrol agent detected the odor of marijuana emitting from the inside of the vehicle and requested the driver to pull into the secondary inspection lane for further inspection."

"Snoop Dogg freely admitted that the marijuana belonged to him and he was placed under arrest by U.S. Border Patrol agents and detained."
