The police searched various homes in Van's Saray district on suspicion of illegal drug activity and seized 39 kg of heroin, said the source, who spoke on condition of anonymity due to restrictions on talking to media.

Six suspected drug traffickers were later remanded in custody, the source added.

One suspect escaped during the operation.
