Infiltration is a major issue in several Indian states. Recently In Parliament, India’s Minister of State for Defense Ajay Bhatt told that there were 441 infiltration attempts made along the India-Bangladesh border in the first six months of 2021and 740 infiltrators from Bangladesh were apprehended and one was killed by the security forces. We all know that India and Bangladesh share a 4,095-kilometre-long border or which around 1,116 kilometres are riverine. Cross-border crimes and infiltration from Bangladesh have prompted the Indian government to adopt a multi-pronged approach to checking illegal activities while increasing surveillance along the border. Completely sealing the border is impossible as there are several villages located close to the border where the demarcation of a no-man’s-land is unfeasible. But, the government uses various technological solutions on an experimental basis for sensitive areas where physical fencing was found to be impractical. Only last month, Tamilnadu police launched a crackdown against illegal Bangladeshi settlers who are reportedly emerged as a “security threat.”
