An Israeli property developer and his wife, arrested in a Koh Samui investigation into alleged nominee-shareholder arrangements, say a Thai lawyer and accountant were responsible for guiding their business setup.
Gal Bieber, 45, and his wife Roni Bieber were arrested by police from Bo Phut Police Station and Surat Thani Immigration. The Samui Provincial Court had reportedly issued 20 arrest warrants for Israeli nationals linked to the wider investigation.
Roni Bieber denied the accusations in an interview with The Jerusalem Post, saying she and her husband had intended to comply with Thai laws and had followed advice from local professionals.
"We respect Thai law and the authorities. All our actions were accompanied by a Thai lawyer and accountant who told us how to do everything and accompanied us when the companies were opened, and the businesses were established.
"We placed our full trust in them and did as they instructed, but when the law changed, they disappeared and took no responsibility, and because they are Thai, they are free from law enforcement," Roni said.
Police allege nominee ownership structure
Investigators reportedly found that Thai nationals had been named as shareholders in companies in order to conceal foreign ownership of land, property and businesses restricted under Thai law.
According to local reports, Israeli nationals were the largest group of foreigners targeted in the operation.
Police allege that Bieber's network used Thai shareholders in a corporate structure to acquire, develop and rent luxury properties on Koh Samui. Many of those properties were marketed towards Israeli customers.
The investigation further alleges that businesses were operated without the required permissions, including an international school and luxury pool villas.
Authorities are continuing to examine financial transactions and investigate other people allegedly involved in the network. Officials are also working to seize and freeze assets connected to the case.
What the case means for foreign investors
The case is a reminder for foreigners buying property or establishing companies in Thailand that local professional advice does not, by itself, determine whether a business structure complies with Thai law.
Roni Bieber said all shareholders, including the Thai nationals, took part in the business activities. The Jerusalem Post reported that she and Gal Bieber had been released on bail while the investigation continues.
