A tour bus associated with Justin Bieber was caught trying to bring marijuana across the boarder of Michigan and Canada.

According to TMZ, a dog sniffed out the drugs on board the bus. The marijuana, along with drug paraphernalia, were seized. The bus driver was issued a citation, but the driver as well as the bus’s passengers were released without further incident.

Although the bus was associated with the Biebz, The Hollywood Gossip reports that the “Boyfriend” star was NOT on board when the drug bust went down.

The Ambassador Bridge checkpoint (the site where the bus was busted) has also busted fellow popstar Rihanna for the same deal.

Bieber has not said anything about the incident, instead Tweeting his thanks for the energy level of his Detroit and Toronto shows.

This is not the first time Bieber has raised some eyebrows. The young star has been causing quite a stir with his erratic “bad boy” behavior. He has been caught spitting on people, urinating in custodial mop buckets as well as reckless driving around where he lives.
