Cambodian authorities are expected to hand a man suspected of masterminding the murder of a British national in a sports club car park in Pattaya over to Thai police on Saturday, police sources said.
The suspect arrested by Cambodian authorities was identified as Toby James Nelham, a 44-year-old British national, an immigration police source said.
Thai authorities were coordinating with their Cambodian counterparts for Mr Nelham's handover which is expected to take place on Saturday.
According to police sources, Mr Nelham is the alleged mastermind behind the killing of Tony Kenway, 39, who was shot dead in broad daylight while sitting in the driver's seat of his red Porsche Cayenne GTS outside Sanit Sports Club Co in tambon Pong, Bang Lamung district of Chon Buri province.
Mr Nelham was a business partner of Kenway's and certain business conflicts led to the murder, police said.
Thai police had sought help from their Cambodian counterparts to hunt down several foreigners suspected of murdering Kenway in Chon Buri province after they were reported to have fled to the neighbouring country.
Two others wanted under warrants issued by the Pattaya court are Abel Caldeira Bonito, 23, a South African who is the suspected gunman, and an accomplice Miles Dicken Turner, 27, a Briton who allegedly drove the motorcycle that spirited the killer away from the murder scene. The two fled to Cambodia the same day as the murder.
