US border agents have found marijuana on a bus with singer Justin Bieber’s tour as it crossed into Detroit from Windsor, Canada.
Customs and Border Protection spokesman Ken Hammond confirmed that the bus was stopped on Sunday as it attempted to enter the US on the Ambassador Bridge, according to the Detroit Free Press.
The singer was not on the bus at the time and performed later that night at Joe Louis Arena.
Mr Hammond said a police dog indicated the presence of drugs on the bus and drug paraphernalia and a small amount of marijuana were found.
He said the bus driver was cited and the vehicle and its passengers were allowed to go.
