Police arrested 13,666 suspects during that first week.[1][2][3] Of those arrested, 1,107 were people listed as island reconvicted criminals.[4] Police held 717 suspects under detention orders for further investigation.[4] Another 1,097 drug users were sent to rehabilitation centres, while 174 suspects faced investigations into illegally acquired assets.[4][2][3]

Police said the week produced 272 kilograms of cannabis within almost 440 kilograms of narcotics.[1][2] Authorities described Sri Lanka as a drug-trafficking transit point in the Indian Ocean.[1][2]

The week-long drive was backed by the military.[1] Local media showed police and soldiers using sniffer dogs to search homes in the capital and elsewhere.[1] Human rights lawyer Hejaaz Hizbullah said the raids were illegal because they were conducted without search warrants.[1][2][3] Activist Ambika Satkunanathan said the searches were not based on evidence and targeted only poor areas.[1][2][3] She added that police were arresting users and small-time dealers rather than focusing on large-scale traffickers.[1][2] Police said raids would pause over Christmas for security duties and resume after Tuesday, a Buddhist holiday.[1]

A police spokesman told the BBC that warrants were not always required to check for drugs.[3]
