Fraudsters have duped students studying abroad out of up to HK$1.5 million (US$191,531) each by accusing them of money laundering and luring them to Hong Kong to buy gold for bogus law-enforcement investigations, prompting a police warning. At least nine victims aged between 19 and 26, who are studying in the United Kingdom, Australia and other countries, have recently fallen prey to such cross-border impersonation scams, according to Hong Kong police.
