The Patiala police on Wednesday arrested two Delhi residents with one kg of heroin worth of `5 crore in the international market.
The masterminds of the drug racket were allegedly operating from Tihar jail.
The accused have been identified as Ashok Kumar from Mangolpuri and Baldev Krishan from Punjabi Camp in Delhi. Both were nabbed when they were entering Punjab through the Shambu border.
SSP Gurmeet Singh Chauhan said that the incident has established the trend that the peddlers are bringing heroin from Delhi.
Questioning of the accused revealed that they had links with smugglers jailed in Tihar Jail. The smugglers, they claimed, are operating the racket.
He said that due to tight vigil in Punjab, the smugglers were now bringing drugs from Delhi, Jharkhand, Madhya Pradesh, and trying to supply in Punjab.
