The short article does not say when the tour buses were allegedly stopped. Nor does it say on which side of the border the incident occurred.

But Rihanna had a concert at the Air Canada Centre in Toronto on March 18 and is scheduled to perform at the Joe Louis Arena Thursday night.

The 25-year-old Barbadian-born singer was apparently not on board any of the 10 buses.

According to the report, an inspector smelled marijuana when the buses pulled in, so  officers boarded a bus with a drug-sniffing dog, who zeroed in on a passenger.

“The real headline,” says the TMZ report, “they only found a ‘small amount’ of marijuana on one person in one bus. Who woulda think?”
