Two Britons killed in horrific double murder after being shot dead and set on fire in rented car in Sweden

It is believed that the pair rented a car from Copenhagen Kastrup Airport before crossing the Øresund Bridge which connects the two countries.

The two victims are believed to have been shot before the Toyota Rav4 was set alight, according to local media.

Swedish police say they "have an idea of who they are", but currently have not been able to identify either of the victims.

The bodies, which were found in the vehicle on a dirt road, are now with forensic examiners.

There is currently no suspect.

According to local news site Aftonbladet, the double murderer is "prepared to strike again".

• Australian 'mushroom poisoner' pleads not guilty to murder after dinner which left 3 dead
• Briton, 93, who suffocated 'darling' wife jailed for 'mercy killing' murder

Authorities have since launched a manhunt across Malmo asking for anyone who saw a black Toyota Rav4 between 11:30am and 2pm in the area on Sunday to come forward. Interpol has also been called in to assist.

Kerstin Gossé, spokesperson for the Swedish Police Authority, said: "'We are interested in talking to people who have seen the car.

"It's about a black Danish-registered Toyota of model RAV4."

She added: "We are working hard with various measures in this investigation to bring clarity to this."

Gossé said that they will cooperate with international police forces if necessary regarding the alleged double-murder.

However, she will not reveal whether the incident could be related to gang crime and has said she will not share any further speculation on the killings.

"So far, we are keeping tight and restrained so that the preliminary investigation can have its way. We have to keep everything open. It is nothing that I can speculate on this early in the investigation," she said.
