HOW THEY WORK

> The BsF seized 280kg of heroin — worth Rs14 billion in the international market — last year along Punjab’s border with Pakistan > Till April 6 this year, the BSF has seized nearly 105kg of heroin worth Rs5.25 billion > Smugglers are known to use three types of methods > The pipe method: They pack heroin in packets of 1kg and push them through the border fence in a PVC pipe > The Conceal and Clear method: They hide a consignment of heroin in agricultural fields inside Indian territory but beyond the barbed wire fence. This is recovered later by farmers who are allowed to go across the fence to cultivate their land along the border > The Throwing method: They throw neatly packed packets of heroin over the fence and run back into Pakistan. The packets are recovered later by Indian smugglers from the agricultural fields
