Justin Bieber's Camp Denies Report That Drugs, Stun Gun Were Found On His Tour Bus

Authorities in Stockholm, Sweden on Thursday told the AP they found drugs and a stun gun on Justin Bieber's tour bus, after a security official at the pop star's hotel smelled marijuana coming from it, leading officials to raid it when it was parked at the venue he was playing at.

However, a Bieber source told RadarOnline.com there were in fact no drugs on the bus; police spokesman Lars Bystrom told the AP that the bus, during the time of the raid, was parked outside of the Globen, where the Girlfriend singer performed Wednesday. No one was arrested in the incident, Bystrom said, and no one has been tabbed a suspect.

"We are in no way saying that the drugs belonged to the artist in question," Bystrom said. "There were 10 people on board, and it could have belonged to anyone."

Last month was a tough one for the singer, as he seems to struggle with his international fame -- and his own humility -- at times: He stormed out of his birthday bash at a London nightclub; was booed by fans after showing up more than two hours late at his first night at the O2 Arena; cursed at paps there; and was accused of assaulting a neighbor in Los Angeles.
