The four arrestees included two men and two women aged between 24 and 38. They were believed to be engaging in triad crime, among whom one was the core member.

They were seized in Tin Yuet Estate of Tin Shui Wai during a raid launched by police on October 29.

Five stolen cars were spotted at an open-air parking lot in Tin Shui Wai, Fung Kat Heung Road, and a warehouse in Yuen Long, with a batch of weapons including telescopic sticks and cleavers found inside.

"The five cars were reported missing from October 7 to 27 in Pat Heung, with a market value of around HK$300,000, " according to Au Yeung Tak, Chief Inspector of New Territories North Regional Anti-triad Unit.

"The criminals would pick old private cars which were parked in remote and isolated places," he said, "after which they would drive the car to their warehouse for reselling."

The arrestees are now in custody for further investigations.
