Drugs and a stun gun have been found on board Justin Bieber's tour bus, Swedish police said today.
Police said a small amount of unidentified narcotics was discovered when officers raided the empty bus under a concert venue in Stockholm, where Bieber was performing last night.
Police raided the tour bus after smelling marijuana when it was parked outside Bieber's hotel.
The drug squad was alerted and conducted the search during the concert.
Police spokesman Lars Bystrom said today that no one has been arrested.
He declined to identify the drug, saying it had been sent to a laboratory for an analysis.
Bystrom said in a statement: "A colleague felt a strong smell of marijuana, like someone had been smoking in the bus".
Bieber is in Stockholm as part of his world tour.
