Intelligence Bureau reports highlight a sharp rise in Bangladeshi nationals attempting illegal entry into India through the porous Indo-Nepal border, shifting from the tightly secured Indo-Bangladesh frontier following Sheikh Hasina’s ouster on August 5, 2024. Key arrests include three Bangladeshis on January 1, 2026, at Raxaul, Bihar, and others in early January, with touts exploiting routes near Bahraich, Gonda, and Balrampur. The Sashastra Seema Bal has deployed 1,700 personnel for intensified combing operations amid fears of ISI-backed terror modules targeting Bihar, West Bengal, and Northeast ahead of Bangladesh’s February 12, 2026, polls and West Bengal’s March-April 2026 elections. From India’s strategic lens, this infiltration threatens demographic shifts and internal security, demanding robust surveillance to counter Pakistan-influenced destabilization from post-Hasina Bangladesh unrest
