In a joint operation, the Gujarat Anti-Terrorist Squad (ATS) and the Directorate of Revenue Intelligence (DRI) have recovered nearly 90 kilogram of heroin worth Rs 450 crore from a shipping container that arrived at the Pipavav port in Amreli district from Iran, the state DGP said on Friday.

To dodge the authorities, the drug syndicate had applied a unique modus operandi in which threads were soaked in a solution containing heroin, which were then dried, made into bales and packed in bags for export, said Gujarat Director General of Police Ashish Bhatia.
