A special BSF team intercepted a woman from near the Nandanpur border outpost area on Tuesday and seized nine gold biscuits worth over Rs 30 lakh from her.
The interrogation of the woman, identified as Nirachan Sekh, led to the troopers apprehending two of her accomplices -- Chhadek Sekh and Rahit Sekh -- from near the international border.
The BSF subsequently launched a joint operation with the police and carried out a raid at a house where the accused used to reside.
"From inside the house, we seized gold ornaments valued at over Rs 1.30 lakh, besides foreign and Indian currencies. We also apprehended one woman from the house," a BSF officer said.
"All the four accused, along with the seized items, have been handed over to the police," the BSF officer added.
The BSF has so far this year apprehended 17 smugglers and seized gold worth nearly Rs 3 crore from along the South Bengal frontier.
