Justin Bieber`s tour bus `busted for drugs`

London: Justin Bieber is apparently embroiled in yet another controversy after police stopped a bus, which was a part of the teen icon`s tour, on Sunday night on suspicions that marijuana and drug paraphernalia was on board.

Chief Customs and Border Protection Officer Ken Hammond told TMZ.com that the vehicle was searched at the border between the American state of Michigan and Canada after a sniffer dog picked up the scent of marijuana from the bus, the Mirror reported.

However, the ` Boyfriend` hit maker was not on the bus, which was halted at the Ambassador Bridge that separates Windsor in Canada and the US city of Detroit.

The drugs found on board were confiscated and the driver was issued a citation.

The driver and passengers were released after the drugs were confiscated.

The ` Baby ` singer`s bus had previously been stopped in Sweden in April after a very strong smell of marijuana came from the bus.
