Stockholm police have found drugs and a stun gun on board of a tour bus used by Justin Bieber.
Police spokesman Lars Bystrom said: “A small amount of drugs and a stun gun were found when officers raided the empty bus parked under the Globen concert venue in Stockholm.”
Lars Bystrom declined to identify the drug, saying it had been “sent to a laboratory for an analysis”.
No-one has been arrested.
Police acted after smelling marijuana coming from inside the bus when it was parked outside the hotel where the singer was staying.
The drug squad was alerted and searched the bus after it carried a group of people to the concert venue.
Police say there are no suspects, and won’t be taking the matter any further.
