British father murdered in a gangland hit in Thailand had become a father for the fourth time just a few months ago as devastated family say they have no idea why he was targeted

The devastated family of a British father-of-four who was shot dead in a tourist spot in Thailand say they have no idea why he was targeted.

Tony Kenway, 39, originally from Southampton, was murdered while sitting in the driver's seat of his red Porsche Cayenne GTS at about 2.10pm today (5.10am GMT) outside an exclusive sports club in Pattaya. 

Paying tribute, his sister Kirsty Kenway, 31, from Southampton, told MailOnline that her older brother had a 'brilliant life' in Thailand and his wife, Pans Kenway, 32, was 'devastated' by what had happened.

Mr Kenway's wife gave birth to his fourth child in September.

Ms Kenway said: 'I don't really know what happened to my brother. He's been in Thailand for years and he's been happily married for five years.

'We speak quite regularly and I visited him over Christmas. We had an amazing time, taking the kids to water parks and he spent a lot of time with his niece. He loved being with his family. He had four children. 

'His stepson is 10 and lives in Spain, his son is nine, and he had two children with Pans, a daughter aged three and a baby that was born in September.

'He absolutely adored his kids and he enjoyed playing with his baby son and he just made sure he looked after his children.'

She added: 'He had a brilliant life out there and he did a lot for charity, and helped build some schools. He had even met the future King of Thailand. He was very clever and did very well. 

'He did a lot of work in IT and was a big fan of sports cars, he was a petrol head. 

'Pans [his wife] is brilliant and she was the light of his life. She's devastated by what's happened. 

'I was the baby sister [in our family] and he protected me from everybody. I was the youngest, and he was the third youngest. We have an older brother, Paul, and older sister, Sarah. 

'We were very close when we were growing up. Tony was like a father figure to me.' 

Police are investigating links between Mr Kenway and foreign 'boiler room' gangs in Pattaya.

Officers collected a single bullet cartridge case and a cigarette butt from the crime scene for examination, the Bangkok Post reported. 

Surveillance video copied showed Mr Kenway walking across the parking area of an exclusive sports club to his Porsche and sitting in the driver's seat.

The gunman, who had been standing nearby, then approached from a different direction. 

Immediately after Mr Kenway gets in and shuts the door, the assailant pulls it back open and leans in, apparently shooting his victim in the head, though the action is not distinctly visible in the video. 

The gunman then ran off to a waiting motorbike with a registration number plate 7992 and sped away.

Mr Kenway's wife, Pans, 32, told police her husband had set up a website design company.

He recently had a business conflict with a shareholder, but she did know if that was the motive for the murder, the newspaper reported.  

The killer was a tubby man, wearing a white T shirt, black jacket, sports shoes and a baseball cap. 

Pattaya is a popular beachside resort town about two hours' drive from Bangkok, and attracts a significant number of Western expatriate residents. 

Mr Kenway had lived in Thailand for seven years, Colonel Jirawut Tantasri said. 

Prior to that he had lived in Marbella, according to his Facebook page, as well as Australia and the United States.

An FCO Spokeswoman told MailOnline: 'We are in contact with the family of a British man following his death in Pattaya, Thailand. 

'Our sympathies are with them at this difficult time. We are in touch with the local police.'  

A spokesman for Nong Prue Police in Pattaya said: 'We have started an investigation and we are looking for the attackers.

'The victim has been identified as Tony Kenway, a 39-year-old man from England. We are speaking with more witnesses.'
