A British tourist has been killed in a brutal attack in Thailand after being turned away from a karaoke bar and chased by bouncers.

Nick Weir, 28, was said to have been acting erratically as he tried to make his way inside the 91karaoke bar in Bangkok before being sent away by staff.

The privately-educated Briton, who managed a company in Salisbury, was alleged to have been kicked out after trying to get inside and asking for service.

Police said he was then chased by two male bouncers on a motorcycle and attacked.

CCTV footage seen by MailOnline showed Mr Weir sprinting down the street before stopping to speak to the pair before trying to get on the back of the bike.

A fight then ensued, with the three men grappling before Mr Weir was thrown to the ground.

The bouncers called the emergency services after Mr Weir was knocked unconscious, police say, but paramedics were unable to save him with CPR.

The Leeds University graduate was pronounced dead at the scene, around 650ft from the bar he had tried to visit.

Officers are now questioning the two Thai men, Phurinat, 32, and Boonchou, 29, over the alleged attack in the Bang Sue district of the capital.

One of his friends, distraught by the news, told ViralPress: ‘I didn’t know. That was not in [his] character at all. 

‘He was so polite, the nicest guy. I can’t believe it. I can’t process this.

‘I knew he was in Thailand. I messaged him yesterday but haven’t heard back from him.’

Lieutenant Colonel Apichai Hwanjit, Deputy Superintendent of the Bang Po station, said today that he had been turned away from the bar by staff.

He then ran away but was pursued by two employees on a motorcycle, who attacked him in a nearby side street.

‘According to the CCTV footage, the two of them together restrained the foreigner and they had a physical confrontation,’ Apichai said.

‘During the scuffle, they pushed and wrestled, causing the foreigner to fall. 

‘We are unsure if there was any pressure applied during the fall that caused the death, so we are waiting for the forensic results.

‘After he fell, the security guard nearby called the police. At the scene, the two individuals who fought with the foreigner remained there and did not flee.’

Officers said they received a report at 2:45 am while the paramedics received a call at 2am and arrived at the scene at 2:20am.

Police said that CCTV showed that he did not appear to be drunk when he arrived at the shop because he was ‘running in a straight line’.

However, they said he was ‘shouting and causing a commotion’.

The two Thai men claim the Brit tried to steal their mobile phone and then tried to mount their motorbike.

Officers are now investigating the final moments of the fight.

Apichai added: ‘Currently, we are waiting for the forensic results to determine whether the deceased was intoxicated or under the influence of any substances.

‘It is crucial for the case to ensure clarity. We are waiting for the blood test results to check for drugs or alcohol. 

‘From the CCTV footage, he did not appear to be in a typical state of drunkenness.

‘He was running, shouting, and causing a commotion, but he wasn’t completely out of control. He ran in a straight line, not stumbling like someone who is drunk.

‘He ran a long distance, nearly a kilometre, starting from the area near the Makro shop, crossing the Phibunsongkhram overpass, and reaching the karaoke bar.’

Officers said that the British Embassy had been informed of the death. 

A FCDO spokesperson told MailOnline: ‘We are providing support to the family of a British man who died in Bangkok and are in contact with the local authorities.’
