The bad news keeps piling up for Justin Bieber. His tour bus was busted in Sweden for drugs.

According to PopCrush, police said that they smelled the odor of marijuana coming from Bieber's tour bus in Stokholm, where he was recently seen with Selena Gomez. Police boarded the bus, and found a small amount of marijuana, and narcotics officers were quickly called in.

TMZ reports that no one was on board the bus when it was searched by police, and the pot was found on the floor of the bus. This makes it hard to tell whose weed it actually is.

And the Bieber drama continues...
