Police in Stockholm, Sweden, say they have found drugs on board a tour bus used by Justin Bieber.
Police spokesman Lars Bystrom says 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, where the pop star was performing Wednesday.
Bystrom said Thursday they have no suspects and no one has been arrested. He declined to identify the drug, saying it had been sent to a laboratory for an analysis.
He says 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.
The incident is the latest in Bieber's tumultuous European tour, which has included a monkey detention, a Holocaust museum furor and a health scare.
In Britain, the 19-year-old singer struggled with his breathing and fainted backstage at a London show. He was taken to a hospital, only to be caught on camera clashing with paparazzi.
In Germany, the Canadian teenage idol had to leave his monkey in quarantine since he didn't have the necessary papers for the animal.
In the Netherlands, Bieber became the focus of intense criticism for writing an entry into a guestbook at the Anne Frank House museum in Amsterdam, saying he hoped the Jewish teenager, who died in a Nazi concentration camp, "would have been a Belieber" - or fan of his - if her fate had turned out differently.
The comment provoked a flood of comments on the museum's Facebook page, with many people criticizing the singer for gross insensitivity.
Anne Frank hid with her family in a small apartment above a warehouse during the Nazi occupation of World War II. Her family was caught and deported, and Anne died of typhus in Bergen-Belsen in 1945. She was 13 years old when she began keeping her diary in 1942. Like many teenage girls, she made a collage of the celebrities of her day -- movie stars, dancers, and royalty -- and kept it on her bedroom wall.
In Norway, where Bieber enjoys enormous popularity, education officials in a remote district rescheduled mid-term exams for high school students so that the singer's fans could attend the concert in the capital and not have to worry about missing the tests.
By Thursday afternoon, Bieber had left Sweden and was in Finland, where he is due to play in the capital Helsinki on Friday evening.
