Members of the public were asked to call police if they spot the vehicle, but not to approach it or interact with the passengers.

Aftonbladet reported that the car, a Volvo V90, had been stolen from the airport on August 1, east of Malmo, Sweden's third largest city and close to the Danish border.

In an effort to track the vehicle down, Danish police cut all links between the island of Zealand and its neighbours.

The Great Belt Bridge, connecting the Zealand with the island of Funen, was shut in both directions around 2pm as the manhunt got underway.

The Oresund Bridge, linking Zealand with Sweden, was partially closed in the direction of Sweden but reopened shortly after.

Ferry services linking the island with Sweden, the Danish mainland and Germany were also suspended.

Copenhagen Central Station was put on lockdown for a short time, but reopened.

Danish police have not said exactly where on Zealand they believe the vehicle is, and have not confirmed why the occupants are wanted.
