A tip-off, officials said, led sleuths of the Delhi zone of the Narcotics Control Bureau (NCB) to a cold storage in Kundli in Haryana's Sonepat district on September 11.
After a raid, they seized 31 packets of one kilogram each of the said drug, which was cleverly concealed in boxes containing 'black raisins', and the narcotic substance was covered with polythene and carbon paper to avoid detection.
"The leads led the agency to an Afghan Baz Mohammad and two Indians D Ramdhani and K Khatri who have been arrested yesterday for smuggling the contraband into the country. While the foreign national hails from Kandhar, the locals belong to Jaipur," an NCB officer said.
NCB officials suspect the contraband entered the country through the Wagah border in Punjab and they said the estimated value of the seized drugs could be well above Rs 40 lakh in the open market.
