Swedish police say that they've found drugs and a stun gun on Justin Bieber's tour bus.

The police confirm that they raided the tour bus after smelling cannabis coming from the vehicle while it was parked outside a hotel. The drug squad were alerted and the bus was raided during Bieber's concert in the Swedish capital of Stockholm.

Officers raided the bus and found a 'small amount of drugs' as well as a stun gun.

But despite the controversy, a source close to Biebs exclusively told omg! that the whole thing has been blown out of proportion, adding: "It's such a non-story. No one was arrested or cited for anything."
