Police are investigating the death of a British pensioner who plunged from a balcony in Thailand.

Cops were called to the D-Beach Hotel in the Thai 'Sin City' Pattaya after Keith Jones, 74, allegedly fell from the 10th floor on the evening of September 6.

The holidaymaker, from Prestatyn, Wales, was found lying face-down in a pool of blood, next to a busy road.

Police blocked the scene with white cloth as they collected evidence from the area.

Phanuthat Thanakasemphakin, a Pattaya Special Affairs officer, said he was working around 20ft away when he heard a loud bang 'like a transformer explosion'.

The policeman said: 'I rushed to see what happened and found the elderly foreigner lying face-down in a pool of blood. He was gasping for air. I tried to help but he soon died.'

Police Lieutenant Manasak Ponyiam of the Pattaya City Police Station said: 'We have inspected the scene and collected evidence.

'The deceased had been staying in room 1079 on the tenth floor of this hotel. We checked his room and found no trace of assault or ransacking.

‘We also checked the security camera for the entire previous day, which showed no one entering or leaving the room except for the victim until his death.

‘We still do not know if it was an accident or suicide.

‘The body was sent to the Institute of Forensic Medicine for a post-mortem exam. We will question hotel employees to determine the cause of death.'

Keith's death is among the latest in a string of fatalities involving falls from hotels in Thailand this year.

On July 19, an allegedly drunk Russian tourist fell to his death from the roof of a pool villa on holiday island Phuket.

Just a day earlier on July 18, an American tourist died in a drunken fall from the 10th floor balcony of a hotel in Chiang Mai.

While on July 2, Austrian guest Mario Frey, 45, died in a drunken fall from the steps of his resort hotel in Surat Thani.

On June 4, British tourist Kerry Bruce, 58, lost her balance and tumbled off the edge of an unprotected walkway while walking up to her room in Phuket.
