Finnish police say they have arrested an 18-year-old man who ordered 22 pounds (10 kilograms) of fertilizer from Poland to make explosives. Local media cited police as saying the man had explained he wanted to make his own fireworks.
The Finnish National Bureau of investigation says agents grew suspicious when the man on Tuesday received a package of fertilizer, which contains ammonium nitrate and can be used for making explosives.
Police said Thursday they arrested him in the town of Lahti in southern Finland after searching his home. They said "during the search a number of things were confiscated and these things were meant to manufacture an explosive device."
Police said the case has no connections to the massacre of 76 people in Norway.
