Authorities arrested five Chinese nationals and confiscated various chemicals believed to be used in making methamphetamine hydrochloride or shabu in a raid at a posh village in Muntinlupa City early Friday.

Philippine Drug Enforcement Agency (PDEA) chief Jose Gutierrez identified the five as Ken Ming Chao alias Lam Tse Kin, 49; Lam Ka Chun, 51; Choi Yiu Kit, 33; Choi Yiu Chun, 33; and Kwok Chi Keung, 42.

Agents of the PDEA swooped down on the suspected shabu laboratory at No. 504, Acacia st., Ayala Alabang Village, around 6:25 a.m., Supt. Danilo Pecana, National Capital Region Police Office spokesman, said.

Seized during the operation were several plastic drums containing chemicals, laboratory equipment, and a glass container with suspected shabu, the “finished product.”

Gutierrez said his men have been monitoring the foreigners for almost a year, since they arrived at the property along Acacia st. in July 2011.

“Based on the laboratory equipment we found, the estimated capacity of the facility is 10 kilograms per production cycle which takes about two to three days,” Gutierrez said in a statement.

It was not the first time for authorities to seize illegal drugs and arrest drug personalities at Ayala Alabang Village.

In September 2008, PDEA agents arrested Richard Santos Brodett and Jorge Jordana Joseph in another house along Acacia st. after the two were found in possession of ecstacy, cocaine, marijuana, and drug paraphernalia.
