Heroin worth Rs 2,500 crore seized by Delhi Police from Faridabad

The heroin haul, described as the largest by the Delhi Police, was smuggled from Afghanistan through Iran's Chabahar port into Maharashtra's Mumbai via Jawahar Lal Nehru port, police said.

"The police have arrested an Afghani national, Hazrat Ali, a resident of Kashmir's Anantnag, Rizwan Ahmad, and Gurjot Singh and Gurdeep Singh from Punjab's Jalandhar. This racket is spread across Afghanistan, Europe and several parts of India," said Special Commissioner of Delhi Police Special Cell Neeraj Thakur was quoted as saying by NDTV.

Four people have been arrested so far, officials said, adding that a narco-terrorism angle is being investigated in the case.

During the raid, over 100 kg of chemicals used for the heroin were also recovered by the police.

"The drugs were then sent for processing to a factory near Shivpuri in Madhya Pradesh and the heroin was prepared with the help of experts in Afghanistan. Following this, the drugs were sold in Delhi, Punjab, Haryana, Rajasthan and Jammu and Kashmir among other states," the official said, NDTV quoted.

The accused arrested in the cases said that the drug racket's mastermind Navpreet Singh, has been operating from Portugal.

Officials said that the accused have revealed that some of the funds for the drug network comes from Pakistan. "This angle cannot be ignored and will be investigated," they added.
