The Border Security Force in Tripura is “contemplating” installation of laser walls at the unfenced riverine patches along India-Bangladesh border to check infiltration bids, official sources said.The security forces have so far been using sensor devices, floodlights and night-vision goggles to guard the international border; the laser walls would further help in plugging gaps in the “vulnerable” areas, a senior officer of BSF’s Tripura Frontier said. “We want to install laser walls to ensure effective border management along the Indo-Bangla border but nothing has been finalised as yet,” he said. A similar project is on the verge of completion in the sensitive areas of Dhubri in Assam, the officer said.Dhubri project “Once the project is successfully implemented at Dhubri, the BSF higher-ups will assess its utility and decide if the model could be replicated in Tripura,” he explained. A real-time communication system, in coordination with the Bhaskaracharya Institute for Space Applications and Geo-information (BISAG), has also been introduced in the State for smooth coordination with the senior officers. “The satellite-integrated BISAG programme facilitates DG BSF to directly interact with the jawans deployed along the border areas. With this, the troops can hold discussions and address queries for better understanding of issues,” the officer stated. Of the total 856-km-long India-Bangladesh border in Tripura, the Centre had approved fencing for 840-km stretch.While 750-km borderline has been sealed, isolated patches — mainly in Sepahijala district’s Sonamura subdivision — still remain unfenced, the officer added.
