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.
