Hong Kong police raided two separate village houses in the New Territories and seized 1,730 cannabis plants said to be worth HK$35 million (US$4.47 million) on Monday.

Acting on an investigation following a tip-off, police found that drug syndicates had rented village houses in rural areas of the New Territories for the purpose of growing cannabis, Ta Kung Pao reported.

Following police raids, two men aged 36 and 37 were arrested in two village houses in Lok Ma Chau and Pak Heung in Yuen Long.

A total of 630 cannabis plants were found in the village house in Lok Ma Chau while 1,100 plants were seized from the house in Pak Heung. In total, the confiscated plants weighed around 120 kilograms.

Police searches also yielded ventilation equipment, solar lights, soil and fertilizers in the houses, which they believe the suspects used to cultivate the plants, news website HK01.com reported.

This is the second largest cannabis farm busted by police in recent years. Police are investigating triad links to the farms, and trying to discover if marijuana from the farms have already been sold on the market.
