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.
