Drugs and a stun gun found on Justin Bieber's tour bus in Sweden Swedish police say they have found drugs and a stun gun on Justin Bieber's tour bus. Police spokesman Lars Bystrom said they found the items when officers raided the empty bus parked under the Globen concert venue in Stockholm, where the Canadian superstar was performing last night as part of a world tour. Today he said they have no suspects and no one has been arrested. He declined to identify the drug, which he said had been sent to a lab for an analysis. Police acted after smelling marijuana coming from inside the bus when it was parked outside the hotel where Bieber was staying. The drug squad was alerted and searched the bus during the concert. Swedish police spokesman Verg Jyllander told Sky News that the singer and his entourage would not be prevented from leaving the country. Bieber, who has had a string of PR problems on his current tour, is due to play St Petersburg on Sunday.
