Fake rooms, props and a script to lure victims: inside an abandoned Cambodia scam centre

Sprawling compound, including mock-up banks and police offices, uncovered by Thai military during border clashes

It is as if you have walked into a branch of one of Vietnam’s banks. A row of customer service desks, divided by plastic screens, with landline phones, promotional leaflets and staff business cards. A seated waiting area and a private meeting room. All of it features the OCB bank’s logo, or its trademark green colour.

This is not a genuine bank branch, however. It’s one of various “mock up” rooms inside a sprawling compound on the Thai-Cambodian border, where criminal groups are accused of using elaborate and industrial-scale fraud schemes to trick victims into handing over money.

The scammers behind the compound targeted people not just in Vietnam, but across Asia, Australia and South America, according to documents and props discovered inside.

Within the six-floor building, in the Cambodian border town of O’Smach, there are rooms designed to look like offices for police forces from Australia, Singapore and China. There are even fake uniforms, badges and scripts to be read over the phone to victims.

The Guardian was given access to the compound on Thursday as part of a media visit facilitated by the Thai military. It bombed the site and seized control of the area during border clashes with Cambodia last year, claiming it was used by the Cambodian military to launch drone operations.

A ceasefire was agreed in December after three weeks of fighting, but Thailand has retained control of the area and other Cambodian villages, despite protests from its neighbour, which has condemned its presence as “unacceptable and unlawful”.

In a statement, the Cambodian information minister, Neth Pheaktra, accused Thailand of using “so-called scam centre concerns as a pretext for actions that undermine Cambodia’s territorial sovereignty”.

The buildings at O’Smach are pierced with bullet holes, and the floors are covered with collapsed ceiling panels, shattered glass and debris. Workers and their bosses appear to have fled as fighting escalated. In their haste, they left behind uneaten food and drinks – as well as vast piles of paperwork, the various tools used to carry out fraud schemes and stacks of what appear to be fake $100 notes.

A tour of the building suggests a highly organised operation. There are rooms filled with desks for 30 people, each padded with noise-cancelling foam. Whiteboards keep track of workers’ targets: “No money, already took 279k,” says a note left beside the name of an apparent victim.

A notebook found in a room targeting Brazilian victims includes daily updates: “For today there is no customer [who] will transfer the money to us – they are trying to grab new customer and talk with old,” reads a November entry.

Scam centres, a hugely lucrative industry, have proliferated across south-east Asian countries over recent years. In Cambodia alone, online fraud schemes are estimated to generate $12.5bn annually, half the country’s formal GDP, according to an estimate by the United States Institute of Peace.

After mounting international pressure, including UK and US sanctions imposed in October against the alleged scamming kingpin Chen Zhi, Cambodia has promised to crack down on cybercrime. Chen, a Chinese-born businessman who built a vast conglomerate in Cambodia, was extradited to China in January. Cambodia pledged to eliminate scamming by the end of April, and says it has closed 200 scam sites.

Documents written in multiple languages, taken as evidence from the O’Smach site by Thai authorities, provide tips on how to lure people into making a fake investment, including through romance scams.

“Create a touching family story (example about losing a love ones, struggling alone etc) to encourage clients to spontaneously express concern and empathy,” says one guide.

Scammers should “create a sense of fantasy by using phrases like ‘future plans’ or ‘we can do this together someday’”, the document reads. It suggests phrases for scammers to use: “I think I’m getting used to talking to you every day.”

Bosses even appear to have refined workers’ scamming abilities through multiple choice quizzes. A test asks workers to fill the blanks: “The standard for finding customers on social platforms are Gender __ Nationality __ Age __. And whether he looks like a real rich man.” The answers? “Male”, “North American” and “40-65”.

Pol Maj Gen Siriwat Deepor, deputy spokesperson for the Royal Thai police, said scam networks were similar in structure to companies – with a training department, and a finance or money-laundering section that deals with money and opens mule accounts. “I think they also have a creative section that will come up with ideas on how to deceive people in each country,” he said, adding that tactics changed by the season.

The scams in O’Smach extend beyond romance fraud. Scripts scattered across desks show how workers presented themselves as members of the police and other agencies from countries around the world.
