The police also arrested two persons - Sukhpal Singh and Sukhdev Singh - in this regard. "These two were taking 25 kilograms of heroin on a motor bike. We have registered case against them," said Ferozepur SSP Dinesh Pratap Singh. Narcotics agencies say that India is a major transit point for drug smuggling to the West where drugs fetch a higher price. Heroin is derived from morphine, a naturally occurring substance extracted from the seedpod of the Asian poppy plant, and appears as a white or brown powder.
