Tripura Police arrested eight Bangladeshi nationals in two separate intelligence-led operations at Maharaja Bir Bikram (MBB) Airport in Agartala on 26 and 27 June 2025, foiling their suspected bid to travel to other states and triggering a wider probe into a possible cross-border infiltration network, officials said on Sunday.

How the Crackdown Unfolded

A senior police official said the first operation was mounted after authorities received credible intelligence that four Bangladeshi nationals would arrive at MBB Airport on 26 June to board a flight to another state. 'Acting on the intelligence inputs, and with the assistance of MBB Airport authorities and staff, we successfully apprehended all four persons before they could board the flight,' the official said.

During sustained interrogation of the first group, investigators obtained fresh leads pointing to the possible involvement of additional individuals. A second intelligence-based operation at the same airport on 27 June led to the arrest of four more Bangladeshi nationals, bringing the total to eight over the two-day crackdown.

Legal Proceedings and Remand Sought

Four of the alleged infiltrators were produced before a local court on Sunday, while the remaining four are in police custody. Authorities have sought a five-day remand for the latter group to facilitate further interrogation and to trace the larger network reportedly behind their illegal entry and movement within India. All eight arrested persons are male, the official confirmed.

What Investigators Are Examining

According to the preliminary investigation, the arrested individuals had planned to travel to Guwahati. Investigators are now examining their complete travel itinerary, the route through which they allegedly entered India, and whether an organised cross-border network facilitated their infiltration and onward movement. Police have seized the accused persons' personal belongings, including mobile phones and other articles, which are being subjected to digital and forensic analysis to identify facilitators and associates.

'We expect to gather more crucial information during the period of police remand,' the official added.

Tripura's Border Vulnerability and Broader Security Context

Tripura shares an 856-km border with Bangladesh and is surrounded on three sides by the neighbouring country, making it one of India's most sensitive states for cross-border migration. While most of the frontier has been fenced to curb smuggling, trans-border crimes, and illegal movement, some stretches remain unfenced.

A Border Security Force (BSF) official noted that the paramilitary force has enhanced vigilance and intensified domination along the International Border since violence erupted in Bangladesh in June–July 2024, particularly after the fall of the Sheikh Hasina-led Awami League government on 5 August 2024.

Union Home Minister Amit Shah has recently announced the launch of pilot projects for Smart Border Management in Tripura, aimed at strengthening surveillance through the deployment of advanced technologies — an initiative expected to bolster efforts against illegal infiltration and other trans-border crimes.

With remand proceedings underway and digital evidence under analysis, the investigation is expected to widen in the coming days as police work to dismantle the suspected facilitation network.
