Fifteen people were arrested in the raids, which were the culmination of a yearlong investigation that targeted properties the New Territories and Kowloon areas of Hong Kong. Among them was the alleged ringleader, 35, a high-ranking member of the Sun Yee On, police said.

Millions Seized

The investigation began after organized-crime activity was observed in Hong Kong’s upmarket Tsim Sha Tsui district, including illegal gambling, drugs, loan-sharking, and extortion. Officers also raided two underground gambling dens tied to the syndicate.

Superintendent Ching Chi-yan, an assistant commander of Yau Tsim police district, referred to the suspect only by the nickname “Lo Yin.” Ching said Lo Yin recruited his wife and girlfriend to help with the operation.

Investigators seized HK$24.7 million (US$3.2 million) in cash and assets from the man’s residence, including HK$16 million (US$2.1 million) in cash and five luxury watches estimated at about HK$7 million (US$900K), along with jewelry, handbags, and assorted foreign currency. Police also froze nine bank accounts holding HK$1.6 million (US$210,000).

Who Are the Sun Yee On Triads?

Sun Yee On is one of Hong Kong’s oldest and most prominent triad organizations with an estimated 25K-plus members worldwide. Its operations span extortion, loan sharking, drug trafficking, and illegal gambling.

Sun Yee On tussles for dominance of those rackets with rival 14K, Wo Shing Wo, and Chiu Chow triad groups.

The operation allegedly moved its money through a finance company that looked legit but functioned as a money-laundering hub, according to police.

Investigators say that from 2016 through this year, 21 personal bank accounts tied to the syndicate pushed around HK$200 million (about US$26 million) in questionable transactions, with many of the account holders showing little or no declared income.

From 2020, three corporate accounts under the same finance company handled roughly HK$960 million (about US$124 million).

The suspects comprised 10 men and five women aged 27 to 62, with five having already been charged and scheduled to appear at Kowloon City Court on Monday, the force said.

Government Crackdown

This case comes as the Hong Kong government intensifies its fight against illegal gambling and organized-crime infiltration.

Under Hong Kong law, most gambling activities are unlawful unless specifically authorized. The only exceptions horse-racing, football betting, and a government lottery.

According to recent figures from the Hong Kong government, from 2021 through May 2024 the police arrested 5,731 people in 2021 for illegal gambling offences, 6,781 in 2022 and 6,101 in 2023.

    Someone forgot to pay their bribes, or got outbid in the bribery game by a rival triad.
