There are several variations of this scam. In many variations of this scam, it involves a phone call from someone purporting to be a government official (e.g. a police officer, immigration officer or court official) or staff from a bank or telecommunication service provider.
In this scam, the caller might claim to be a government official, an employee or representative of a Chinese bank or courier company. The caller might claim that your identity was used to send parcels containing fake passports or weapons, or to apply for overseas credit cards. They then refer you to another caller claiming to be a Chinese official, who will ask — or even threaten — you to give them personal information such as your passport or bank account number, internet banking credentials or One-Time Password (OTP).
