Police arrested 6,400 people and seized cash, dangerous drugs and illicit goods amounting to $410 million during an anti-crime joint operation with their Guangdong and Macau counterparts.

Codenamed “THUNDERBOLT 2023”, the tripartite operation was conducted from June 12 to September 21.

During the operation, Hong Kong Police conducted searches with various departments at about 3,100 locations, neutralising gambling dens, vice establishments, unlicensed bars and loan-sharks companies.

A total of 6,400 people, aged between 10 and 85, were arrested for triad-related or organised offences, from wounding and blackmail to trafficking in dangerous drugs and money laundering.

Among the arrestees, 849 were Mainlanders and 471 were non-ethnic Chinese.

Hong Kong Police also seized $12 million in cash suspected to be crime proceeds as well as dangerous drugs worth more than $350 million.

The intelligence-led enforcement operation was aimed at combating illegal activities of triad societies and organised crime syndicates, neutralising cross-boundary crimes, and interdicting the criminals’ sources of income.
