Two Brits are shot dead in rented car and set on fire in double murder after hiring a vehicle in Denmark and driving to Sweden

Two British citizens have been found shot dead in a burned-out car in Sweden in a horror case police are now investigating as a double murder.

The bodies were recovered after firefighters were called to the scene of a blaze on a dirt road at Fosie Industriby in the coastal city of Malmö on Sunday afternoon.

It is believed that the victims rented a car at Copenhagen Kastrup airport before they were found in the nearby Swedish city across the border.

They are understood to have been shot before the car was set alight, local media reports.

The identities of the deceased have not yet been shared, but police officials say they 'have and idea of who they are'.

They are now asking for tips about a Danish-registered black Toyota Rav 4, with Interpol also reportedly involved in the case.

The bodies will be examined forensically this week as police look to confirm the identities and notify the next of kin.

They are now asking anybody who saw the black Toyota between 11.30am and 2pm on Sunday, July 14 to get in touch.

The victims were last seen travelling past the Öresund Bridge toll station on Sunday afternoon.

Police reportedly now fear that there could be more acts of violence to come, according to Swedish tabloid Aftonbladet.

But Kerstin Gossé, spokesperson for the Swedish Police Authority, said that there was nothing she had heard internally to that effect.
