It was on March 27 that a dog found a bag hidden in the forest at Mariehem in Umeå, by the water tower.

"The dog becomes attentive and sniffs eagerly and dives into a tree. I saw that it was trampled under the tree where the dog marked. I became suspicious and checked a little closer, says the dog owner in police interrogation.

"Generally dangerous not to replace"

Police arrived at the scene and seized the drugs. Prosecutor Anders Norberg decided that the drugs should be replaced with substitutes.

"In this case, we exchanged just over four kilos of hashish for wooden cubes. If there are such large quantities of drugs, we have to replace because of the general danger, we have to play it safe," he says.

The police kept a watch on the scene and the very next day two guys in their 20s came to the scene to pick up the bag. They were arrested there and then and are now charged with narcotics offenses.

In Vännäs, a man was recently acquitted because the drugs had been replaced by sugar. But prosecutor Anders Norberg believes in a conviction in the Mariehem case.

"There are many things that match. Partly it is the time aspect, that the perpetrators "picked up" the drugs the next day, but also that one person's fingerprints were on the real drug.

Worth about half a million on the street

The suspects are vague when questioned by the police. Both repeatedly respond that "there's not much to say," "no comment," or "I don't know" to the interrogator's questions.

The street value of drugs is about half a million. Sentencing is expected on June 13.
