Justin Bieber has been embroiled in a drug scandal following reports claiming Swedish police found narcotics aboard the singer's tour bus.
On Wednesday, police in Stockholm obtained a search warrant and reportedly raided Bieber's bus which was empty and located in the parking garage of the Globe Arena – where the singer was performing at the time. Police reportedly found a small amount of narcotics on the floor along with a stun gun, however no charges were made, according to TMZ.
"[Police] first detected a 'strong smell' of marijuana coming from the bus as they were controlling the huge crowd that had gathered outside Bieber's hotel," Police spokesman Lars Bystrom told Mail Online.
The drug squad was immediately alerted and police later raided the empty bus while Bieber, 19, performed a concert as part of his world tour.
While some media outlets claim that the substance found by police was marijuana, Bystrom has refused to identify the substance because it has been sent to a laboratory and is still undergoing analysis.
No charges will be made because police are reportedly unable to determine who the substance belongs to.
The incident comes just three months after Bieber was infamously photographed smoking a suspicious looking cigarette, which he has since apologized for.
The pop star was seen smoking at a Newport Beach hotel on Jan. 2, reportedly with rapper Lil Twist and an unidentified woman. Sources claim that both Bieber and Lil Twist, real name Christopher Moore, were smoking marijuana, according to TMZ.
"Everyday growing and learning. trying to be better. u get knocked down, u get up," Bieber tweeted Jan. 5 after receiving backlash for the photos.
Another cryptic tweet read, "i see all of u. i hear all of u...i never want to let any of you down. i love u. and..thank u...like i said...2013...new challenges. new doubters...Im ready."
In addition to the smoking scandal, Bieber was criticized for lunging at a paparazzi photographer while touring the U.K. recently. He also could face battery charges for an incident involving his next door neighbor.
