Weed Found on One of Rihanna’s 10 Tour Buses

Rihanna’s tour buses were stopped at the border between Michigan and

Canada … and law enforcement sources tell TMZ that authorities found

weed.

A total of 10 buses were stopped at the Ambassador Bridge, which

separates Windsor, Canada and Detroit. Inspectors smelled marijuana on

one of the buses and initiated a secondary, bus-to-bus search.

Inspectors then brought out the drug-sniffing dogs, and one of them

made a beeline for a passenger and authorities found he was in

possession of pot. He was cited with a civil penalty, according to TMZ.

Rihanna was not on any of the buses.
