Snoop Dogg was held overnight by Swedish police on suspicion of using illegal drugs, reports SkyNews.
He was later released, but could face more trouble if a test comes back positive for drug use. The results should be back in a few weeks.
Matts Brannlund, of the Stockholm police, explained that Snoop was picked up on his way to a party:
"He was deemed to be under the influence of narcotics.
"He underwent some tests that will now be sent away for analysis. In two to three weeks, we'll know if he was on something."
The officer also revealed that drugs were found in the car Snoop was travelling in, but it was unclear both what they were and who they belonged to.
