In the biggest seizure of heroin so far, customs officials in Amritsar on Monday seized nearly 101 kg heroin from cement bags that arrived from Pakistan on a goods train.
Customs department sources said this was the single biggest seizure of heroin at the railway dry port.
The officials also seized over 500 rounds of live ammunition.
The heroin is valued at over Rs.500 crore in the international market, the sources said.
The goods train had brought the cement from Pakistan.
"The heroin was packed in packets and put inside the cement bags. Further investigations are on," said a customs official.
India and Pakistan do limited trade by train and trucks through the Attari-Wagah land route border, 30 km from Amritsar.
