According to high-placed sources in the BSF, 22,000 people entered India with visas through the said check-point in September-October last year, the report said. This year, the number has increased by another 10,000, the report added. The BSF said more forces were being deployed along the porous borders in four districts in West Bengal to increase the surveillance.
The ongoing turmoil in poll-bound Bangladesh is believed to be the reason behind such exodus. The comparatively easier procedure of getting the visa has also encouraged the movement.
The report also added that the BSF has detained over 3,300 illegal immigrants from Bangladesh and have recovered over a lakh cattle and seven lakh bottles of phensedyl from them, the report said.
