A British man bled to death on holiday in Thailand after cutting himself on a mirror in a shop. Iain Mackay, 40, is believed to have argued with his Thai girlfriend moments before his death. He is also understood to have clashed with a man who was seen talking to his girlfriend at a bar. The incidents happened in Hua Hin, a coastal town and beach resort 120 miles south-west of Bangkok. Tragic: Iain Mackay, 40, (pictured) is understood to have got into a fight at the Hua Hin resort, 125 miles south of Bangkok, after discovering the woman chatting with another man at a bar in the coastal city . Thai police said Mr Mackay, from Stornoway, Scotland, was in a rage when he cut himself with a piece of glass at a shop near to the bar where he had spotted his girlfriend. Onlookers called paramedics after he was found bleeding profusely at the shop but they were unable to save him. He later died in hospital. Officials said that no crime had been committed. However, friends of Mr Mackay claim that he had clashed with another man who had been talking to his girlfriend moments before his death, the Press and Journal newspaper reported. Others said that Mr Mackay had posted links to his girlfriend’s Facebook page before his death in which she was pictured with another man. One friend said: ‘Iain was obviously upset and referred to the woman who seemed to be his own girlfriend and a mystery man as lovers.’ Those close to Mr Mackay said he had been in a relationship with his girlfriend for several years. Mr Mackay, an underwater research specialist, is believed to have been employed by seismic research company Polarcus, which is based in Dubai. Location: The resort where Mr Mackay died is in Hua Hin (pictured) - a coastal city 125 miles south of Bangkok . Sources at the company confirmed that Mr Mackay was on leave from his vessel and had told colleagues that he planned to spend his time off in Thailand. Thai officials said that Mr Mackay had died at 3pm on Saturday but relatives claim that they were told of his death on Friday. The Foreign Office also confirmed that Mr Mackay had died on Friday. A spokesman said: ‘We can confirm the death of a British national in Hua Hin, Thailand, on April 3. We are providing consular assistance to the family at this sad time.’ Mr Mackay’s death comes nine years after a British former public schoolboy was murdered after splitting with his Thai wife at the Hua Hin resort. Toby Charnaud, 41, was beaten to death with an iron bar and wooden staves by relatives of his ex-wife, Pannada Laoruang, in August 2006. Laoruang then helped them burn his body before chopping it up and scattering the remains. A Thai court at the time heard how Mr Charnaud, who was educated at Marlborough College, sold £2.5million Latimer Manor estate near Chippenham, Wiltshire, after falling in love with 35-year-old Laoruang, whom he met in a Bangkok bar while on holiday. Last year British students Hannah Witheridge, 23, and David Miller, 24, were murdered on a beach on the Thai island of Koh Tao. Two Burmese men have been charged with their murder.
