Danish police say one man was killed and another suspect wounded in a shootout after police attempted to search a boat that they said was carrying a large haul of marijuana.

Police spokesman Thomas Kristensen says one policeman was also wounded in the operation in Aalbaek harbor, located in northern Denmark, and one other suspect was apprehended.

Kristensen said Monday that police found 250 kilograms (550 pounds) of marijuana on the boat.

The nationality of three suspects was not immediately clear, although Norwegian media were reporting that the three were from Norway.

Such shootouts are extremely rare in Denmark. Kristensen said a special bureau will take over the investigation to determine whether police were justified in using their firearms.
