The halves of two bodies, one belonging to a female Swedish politician, are discovered in the middle of the Ø(⏺)resund Bridge, which connects Copenhagen in Denmark with Malmö in Sweden. The body, cut in half at the waist, has been placed precisely on the border between the countries, thus falling under the jurisdiction of both the Danish and Swedish police agencies.
