Ilocos Sur police destroyed about ₱15 million worth of marijuana in separate assaults on a 3.7-hectare plantation in Barangay Caoayan, Sugpon, near the Benguet boundary.[1] Provincial director Senior Superintendent Mario Subagan said barangay officials and residents had tipped the force before teams under Senior Inspectors Mario Castillo and Fabiano Sudario moved in.[1]

On the first day of the operation, guards described as New People’s Army rebels fired on the police before pulling back, and the raiders seized 40,000 plants.[1] A second assault recovered another 35,000 plants, which were burned in bulk.[1] Subagan’s report, carried on 22 March 2004, does not say anyone was arrested or charged.[1]
