A British father allegedly killed a paedophile Russian with a single punch for propositioning his underage daughter in Thailand this weekend.

The 34-year-old Brit was attending a pool villa party with his daughter, 15, when Igor Yasilyev, 36, reportedly began flirting with her in Pattaya in the early hours of May 27.

The drunk Russian was said to have whispered to the teenager that he wanted to have sex with her, infuriating the British father who smashed him in the face and sent him falling headfirst onto the ground.

Police Captain Parnsarn Krongsit of the Pattaya City Police Station said cops received a report at 3:16am and went to the scene with medics where they found four male and two female foreigners, including the unconscious Russian who was lying on the floor with blood pooling around his head.

He was rushed to a branch of the Bangkok Hospital in Pattaya but died of his injuries soon after.

Police Lieutenant Colonel Nawin Thirawit, superintendent of the Pattaya City Police Station, said: 'An arrest warrant has been issued for the British man by the Pattaya Provincial Court. He is wanted for assaulting another person resulting in death.'

The father, reportedly from Wales, was arrested on Monday afternoon at his home in the Sattahip district, around 10 miles from the pool villa.

He told police: 'I did not think my punch would lead to the man's death. I regret my actions.'

Meanwhile, his Thai wife, 28, said she had also attended the party but left early to go to work. 

At around 3am, she claimed she received a text from her husband saying he wanted to go home.

She said: 'I returned to the villa and found him walking along the street, so I took him back inside.

'When I asked him what happened, he told me that while they were drinking, the Russian man started to sexually harass our daughter, even though his own wife was also there at the party.

'The harassment escalated until the man finally propositioned our daughter. This angered my husband so he punched him once and knocked him out.'

An acquaintance of Yasilyev said both men met each other for the first time at the party.

She said: 'They were drinking together normally until a row broke out. I didn't know what nationality the man was, but he punched Mr Igor, who hit his head on the ground. 

'I was so shocked because there was a lot of blood.'

Police detained the British attack and brought him to the Pattaya Police Station to face legal charges.

The shocking incident comes just days after two British tourists were brutally beaten by a trio of furious bouncers outside a bar in Pattaya last week after a disagreement over the bill saw tensions spill over and lead to a brawl in the street.

The Brits had been drinking alongside several escorts at the notorious Soi 6 road in red-light city Pattaya on Friday evening when they allegedly began arguing over the bill with staff.

They claimed that the bar had tried to scam them by inflating the receipt, and three security guards intervened when the tourists began directing their anger at the barmaid.

After a few minutes of pushing and shoving a savage fistfight broke out when the guards snapped and attacked two of the men - one in a grey shirt and one in a white shirt - dragging them into the street and knocking them both to the ground. 

The guards were seen kicking at the legs and chest of the man in white - before another bouncer came running in from the side and blasted him in the head with a full-force kick, immediately knocking him unconscious. 

He was seen lying motionless for minutes after the vicious blow, with onlookers unable to revive him.

The victim's condition is not known and police yesterday refused to give any details of the alleged victim as they scrambled to protect the image of the city, which relies on tourism.

Footage from another angle showed how his compatriot in the grey shirt was also briefly knocked unconscious by another bouncer, who kicked him in the jaw as he tried to stand up after being tackled to the ground.

That bouncer can be seen walking away with a bloody nose.  

Speaking today, Sergeant Major Arthon from the Pattaya City police station, said that the three security guards have since been warned about their conduct but they have not been arrested or charged.

He said: 'The tourist in the video who was attacked has not filed a police report, so we cannot assign an investigating officer. There's no case open until they complain. We've had a look around but can't find them.

'Yes, we're still checking CCTV to see what happened to them. There are rumours that he is in intensive care but we haven't heard anything from hospitals.'

One of the sex workers from the bar where the incident unfolded said that the group of three men disputed their drinks bill, which came to around 2,8000 Baht (£60).

Bar hostess Samorn, 38, said that the three men had paid for two escorts to drink with them.

She said: 'Two of the tourists had paid their bills, but another had not and changed his seat several times.

'I asked them to pay the bill, but the tourist in the white shirt argued that he had already paid. I explained that the money I was asking for was the payment of someone who had not paid and not his own bill.

'They insulted me and said the bar was trying to scam them, so I called the security over and told them the tourist would not pay his bill.'

CCTV shows how the bills were settled but the tourist in a white t-shirt then pushed a security guard and the fight escalated.

Police Colonel Nawin Thirawit, superintendent of Pattaya Police Station, said today that the bouncers' actions had tarnished the image of Pattaya.

They were invited to the police station and apologised for 'damaging the image of the country'.

The policeman said: 'The security guards should have prevented the incident and reported it to the police.

'Anyone who works in this industry must keep their emotions in check and focus on preventing incidents rather than attacking people.

'Cases like this can damage the reputation of the city and deter tourists from visiting.'

Helicopter Bar, which is understood to have British owners, did not respond to requests for comment. Several other bars on the same street are also owned and managed by the company Nightwish Group.

Pattaya emerged as a nightlife destination in the 1960s when Thailand fought alongside the United States and provided them with land for eight military bases.

It has since grown into a sprawling red-light city that attracts holidaymakers and hedonists from across the world, but it is particularly popular with Brits.
