The Border Security Force (BSF) on Monday seized 13 kilogram (kg) heroin from two different locations at the India-Pakistan border in Amritsar district.

Pakistani smugglers tried to cross over to India under the cover of a thick blanket of fog. A patrolling party of the force observed some suspicious movement at the Indo-Pakistan Border Out Post Daoke and Barowal and opened fire as some people were seen moving back towards Pakistani territory, an official said.

A comprehensive search operation was launched at Daoke, wherein the troops seized 12 kg heroin, while one kg heroin was seized at Barowal Border Out Post, the official said.

The BSF official said no arrest had been made while further investigation was underway.

The BSF was looking for the person who was supposed to collect the drug consignment on the Indian side, the official added.
