Umeå police forced to leave real drugs at crime scene instead of exchanging it for a substitute. Supreme Court issued a ruling in a case concerning extremely serious weapons offences in Södertälje.

Head of investigation Thomas Palmgren: "Must be twice as many police" supplying real drugs requires significantly more resources from the police. "It's the nightmare that it's going to happen," says the head of the reconnaissance. "The risk of leaving the drugs is partly that they end up on the street"
