Police in southwest China's Guizhou Province have seized a large amount of equipment and 900 kilograms of raw materials for drug production and arrested more than 30 suspects, police said Thursday.

In July 2015, police in Guizhou's provincial capital Guiyang began to investigate the activities of a drug gang headed by a suspect surnamed Li. The gang operated a drug lab in a remote village in north China's Hebei Province.

In October 2016, police raided the lab and arrested Li and five other suspects. They also confiscated over 900 kilograms of raw materials and equipment. A major member of the gang, surnamed Zhang, however, evaded capture and fled the scene.

On Feb. 1 this year, the police were tipped off that Zhang had resurfaced in Guiyang and was in the process of setting up another lab. Zhang had also secured sales with drug dealers in Malaysia.

Zhang and 30 other suspects were arrested in Guiyang on Feb. 7.
