The Border Security Force recovered 40 gold biscuits weighing 4.6 kg and valued at Rs 2.57 crore from a swamp, informed BSF officials on Monday.According to BSF officials, a few months ago, there was an attempt to smuggle contraband through the pond. Seeing the on-duty jawans, however, the smuggler jumped into the pond. The troops informed their company commander after which the smuggler was pulled out of the water and searched. However, nothing was recovered from him."A massive search operation was launched after cordoning the area off. However, because of the wet and watery area, the jawans could not find anything, and the smuggler was allowed to leave," said an official.After a few days, the force received information that the smuggler had hidden a large consignment of gold in the pond before fleeing. Personnel from the BSF's South Bengal Frontier seized more than 113 kg of gold on the border in 2022.
