A British pensioner has been killed in a horror motorbike crash in Thailand.

Keith William McVeighty, 83, was riding along the motorway when a car suddenly pulled out from a side road in Chiang Mai on Sunday morning.

CCTV footage shows how the female driver accelerated across the road onto the outside lane straight into the path of Keith, from the Isle of Man.

Shocked Keith pulled his brakes but was unable to avoid smashing into the back of the silver Mazda SUV.

The motorbike lover, an experienced rider who had previously competed in the TT race, was flung onto the roof of the vehicle before falling onto the road. His helmet came off partially in the collision.

Paramedics rushed the ex-pat to the city's Hang Dong Hospital but he was pronounced dead several hours later. His family is believed to have been informed.

Investigating officers are now questioning the female driver of the car, a Chinese woman from neighbouring China, who was visiting the region. They are reviewing CCTV of the crash to check if she had been driving recklessly.

Police Captain Jetsada Pankaew from Hang Dong police station said: 'I am in charge of the investigation. We are interviewing the driver and checking CCTV cameras to find out what caused the accident. If they were at fault they will be prosecuted in accordance with the legal process.

'The motorbike rider died due to the injuries he suffered in the crash. He had a very powerful big bike but he was very confident riding on the road. The bike has been checked as evidence.

'We have followed the normal procedure and the British Embassy has been informed of the death.'
