The drug was to be transported to Punjab from Kashmir, they said.
Acting on intelligence inputs, the DRI officials intercepted a vehicle at Batwara area in Srinagar on Wednesday and arrested three Punjab-based smugglers, a statement issued by the agency said.
"Rummaging of the intercepted car resulted in recovery of 627 grams of high quality heroin. The contraband was concealed in a specially designed cavity.
"The narcotic material and the car have been seized by the DRI and three Punjab-based smugglers have been arrested," the statement issued by the agency said.
Preliminary investigations suggest that the seized heroin was sourced from across the border, it said.
