Danish police say "a considerable amount" of cocaine has washed ashore along the Scandinavian country's North Sea coast but they will not release details due to an ongoing European investigation.

Police spokesman Hans Roost says German police have made similar findings, adding the drugs could have been washed ashore by currents from a great distance and likely were not intended for the Danish market.

Roost said Friday the drugs were packed in bags and boxes but would not comment on local media reports that up to 100 kilograms (220 pounds) washed up in Denmark alone.

Roost says the street price for one kilogram (2.2 pounds) of cocaine in southwestern Denmark is up to 400,000 kroner ($72,000), depending on purity.
