A new tactic for scamming money from Hongkongers is gaining popularity, police have said, with con artists increasingly asking their victims to download computer software which lets the thieves move money from their online bank accounts. An engineer, 38, fell victim to the con last month, losing 1.5 million yuan (HK$1.7 million). A scammer called the Kwai Chung resident, who moved from the mainland several years ago, on April 4, claiming to be a Hong Kong immigration officer. The man accused his victim of involvement in a mainland money laundering case. He transferred the call to another man who claimed to be an officer from Shanghai’s Public Security Bureau. Hong Kong police said the man was asked to go to a hotel in Huangguan, Shenzhen, to help with an investigation, and he did so.

On April 6, the victim found 1.5 million yuan had been taken, but did not call police immediately. He realised he had been cheated when no one contacted him and the money was not transferred back to his accounts. He called Hong Kong police on Sunday. Another source said the tactic in question surfaced late last year, but had been sucking in more victims recently. Hongkongers continue to fall for phone scams, despite repeated warnings from police not to provide private bank information over the phone, the internet or other channels.

The largest loss ever recorded in the city for a phone scam came in March last year , when a Hong Kong businessman from Yuen Long was cheated out of HK$58 million. Typically, scammers call victims and tell them a parcel they mailed has violated mainland laws, before being passing them onto someone claiming to be a mainland official. They instruct the victim to prove their willingness to cooperate by transferring money to a mainland bank account. Hong Kong police said mainland law enforcement officials would never ask someone to hand over money to prove their innocence, or ask them to provide online banking passwords over the phone or via internet.
