13 Foreigners Arrested in Raid
Thai authorities, in collaboration with the Australian Federal Police, raided a luxury residence in Samut Prakan’s Bang Phli district on June 16, 2025, arresting 13 foreign nationals involved in a sophisticated call centre scam. The group, comprising five Australians, six Britons, one Canadian, and one South African, allegedly defrauded Australians of approximately 32 million baht over the past year, marking a significant blow to a long-running fraud network.
Targeting Australian Investors
Fake Bond Schemes Uncovered
Operating as a “boiler room,” the gang posed as legitimate financial firms, cold-calling Australians to pitch fraudulent bond investments promising 7-10% annual returns. The scam, which targeted over 14,000 victims, used high-pressure sales tactics and forged documents. Funds were reportedly laundered through cryptocurrency, contributing to losses exceeding 4.45 billion Australian dollars over four years, as reported on June 17, 2025.
Relocation from Indonesia
Leaders Evaded Prior Raids
The syndicate, led by Australian Mark Dennis, 54, and Briton Mark Howship, 56, relocated to Thailand in early 2024 after evading authorities in Indonesia. Thai police, alerted by Australian investigators, tracked the group from Pattaya to Bangkok, where they established their base in a 70-million-baht mansion rented for 120,000 baht monthly. The heavily secured property served as the nerve center for their illicit operations.
Seized Evidence Exposes Scale
Workstations and Scripts Found
During the raid, authorities seized 58 items, including computers, mobile phones, network equipment, and investment scripts detailing the scam’s playbook. The ground floor of the house was converted into an office with workstations, where suspects followed Sydney business hours, starting at 5 a.m. local time. Documents revealed contact lists of thousands of Australian victims, underscoring the operation’s extensive reach.
Immigration Violations Confirmed
Visas Revoked, Blacklist Imposed
None of the suspects possessed valid work permits, having entered Thailand on various visas, including those for retirement and education. Immigration officials confirmed the suspects had not overstayed but announced their visas would be revoked, and they would be permanently barred from re-entering Thailand. This crackdown highlights Thailand’s commitment to curbing transnational crime within its borders.
Suspects Deny Allegations
Claims of Legitimate Employment
In initial interrogations, all 13 suspects denied wrongdoing, claiming they were hired through online job postings with salaries of 64,000 baht monthly plus commissions. They stated they believed they were working for a legitimate investment firm, tasked with contacting potential investors using provided lists. However, Thai and Australian authorities assert the group knowingly participated in a criminal enterprise.
Regional Context of Scam Crackdowns
Thailand’s Ongoing Efforts
This arrest follows intensified regional efforts to combat scam centres, with Southeast Asia emerging as a hub for such operations. Thailand’s proactive measures, including joint operations with international partners, aim to disrupt these networks. The Samut Prakan raid, part of Operation Firestorm, sets a precedent for tackling sophisticated fraud schemes, protecting vulnerable communities in Australia and beyond.
