The kingpin said he was active in supplying heroin procured by him from Malda-based supplier -- Risawul to Delhi-NCR for the past decade. He was introduced to Risawul by a notorious local supplier of the area, Kishor, who is now in jail, the DCP said.
The heroin is brought from Malda as there is large scale illegal cultivation of opium in the area surrounding Kaliachak, which was in news recently for widespread rioting allegedly by the drug mafia, he added.
Malda district has emerged as an "epicenter" of illegal drug and counterfeit currency trade due to its strategic location along the international border, he said.
It is alleged that a large portion of this drug money goes into buying sophisticated weapons smuggled through the porous Bangladesh border, the officer added.
