Police are hunting a father and son after a gang tried to burn an elderly couple alive after trapping them in a car.

George and Martha Stewart were targeted while visiting their daughter and grandchildren at Longman Caravan Park in Inverness on August 19.

The pair tried to escape with their son before their car was rammed up an embankment, knocking Mrs Stewart unconscious.

The gang then poured petrol through the car's window before setting them alight.

Mr Stewart, 67, was left with 30% burns following the attack and Mrs Stewart, 61, suffered serious facial injuries.

Officers are now looking to trace Donald Stewart Snr, 47, and Donald Stewart Jnr, 24, in connection with the incident.

Both men are based in the Highland and Moray areas, however, it is believed they may also travel further through Scotland and the UK.

Donald Stewart Snr is described as being white European, approximately 5ft 11in tall, with blond hair cut very short. He has tattoos on his right arm including 'Kelly,' a heart scroll and an image of a devil.

Donald Stewart Jnr is described as being 24-years-old with red hair, a thin build and psoriasis patches on his face. Both men are known by the nickname "Blocker".

Detective Inspector Eddie Ross said: "Significant police enquiries have been carried out in relation to this incident and in an effort to trace the two men.

"I would ask people not approach either man if you believe you have seen them. Instead please call Police Scotland as soon as you can."
