The Department of Narcotics Control (DNC) has arrested three men for trying to distribute Tk1 crore worth of cannabis brought in from the US through the state-run post office, the narcotics department said Tuesday.

DNC Director General Mustakim Billah Faruqui briefed reporters about the operation at DNC headquarters in the capital on Tuesday.

Mustakim said they are trying to extract information from the arrestees about other people involved in the narcotics trade.

On a tip-off, DNC seized the narcotics consignment on Sunday at the Bangladesh Post Office headquarters in the capital. Later, based on the receiver’s data mentioned on the parcel, DNC arrested three youths: Rasel Mia, 20, Ramjan Mia, 21, and Mohammad Imran alias Raaj, 20, from Dhaka district’s Ashulia area.

The arrestees admitted their involvement and were engaged in distributing narcotics in the capital for a long time, DNC said.

The seized parcel was sent from the Maryland state of the US, and contained 1,350 grams tetrahydrocannabinol mixed kush, 252 grams cannabis chocolate and 600 grams of cannabis cake.
