NIA Manipur attack arrests have increased to three fresh detentions across two separate cases involving an armed ambush on the then Chief Minister’s convoy and an IED attack in Bishnupur district. The National Investigation Agency arrested two accused in the convoy case and one accused in the IED case.
The latest action covers incidents from 2024 and 2026. Moreover, the arrests have expanded the investigations as the agency works to establish the alleged roles of the accused and identify other people linked to the cases.
The arrests also involve separate Special NIA Court proceedings in Manipur. Both investigations remain ongoing, and the accused remain subject to the judicial process.

NIA Manipur Attack Arrests Expand Convoy Ambush Investigation
The NIA Manipur attack arrests include Jangminlun Singson alias Franky, 44, and Thangjoel Haokip alias Thangboi, 21. The agency arrested the two men in connection with the June 10, 2024 armed ambush on the convoy of then Manipur Chief Minister N. Biren Singh.
The attack occurred along National Highway 37 near K. Sinam village in Kangpokpi district. According to reports, armed assailants targeted the convoy, while two security personnel sustained serious injuries. Government vehicles were also damaged during the incident.
The NIA took over the investigation in July 2024 after the case was initially registered at New Keithelmanbi Police Station. Since then, the agency has investigated the alleged wider conspiracy behind the attack.
Singson and Haokip are the third and fourth accused arrested in the convoy ambush case. The NIA has alleged that the two men played roles in planning or facilitating the attack and had links with other people allegedly involved in the conspiracy.
Both accused had previously been arrested by the agency in another case. However, their alleged involvement in the convoy ambush emerged separately during the ongoing investigation.
The two men were produced before the Special Court for NIA Cases in Thoubal. The court remanded them to eight days of police custody, allowing investigators additional time to question them and examine their alleged connections.
The NIA has said that the investigation will continue. Therefore, the latest arrests do not represent the conclusion of the case.
IED Blast Case Leads to Fresh Arrest in Bishnupur
The NIA Manipur attack arrests also include Thangmang Haokip, 48, from Churachandpur. The agency arrested him in connection with an IED attack at Tronglaobi Awang Leikai in Moirang, Bishnupur district.
The incident occurred on April 7, 2026, at a residential house. According to the NIA-linked reports, an explosive device struck the house and injured members of a family. Two children later died from their injuries.
Haokip’s arrest followed an earlier arrest in the same case. The NIA had arrested S. Palal Thadou Kuki on August 12. Investigators subsequently arrested Haokip on September 25.
The agency has alleged that Haokip was connected to the attack. However, those allegations remain part of an ongoing investigation and must be considered through the legal process.
An Imphal Special NIA Court remanded Haokip to 12 days of police custody. The agency is continuing to examine the circumstances surrounding the attack and the alleged involvement of other individuals.
The investigation was initially handled by Moirang Police Station. The case later moved to the NIA on April 23, following the incident and subsequent investigation into the wider circumstances.
The agency registered the case under relevant provisions of the Bharatiya Nyaya Sanhita, the Explosive Substances Act and the Unlawful Activities (Prevention) Act, according to reports.
Consequently, the investigation now covers multiple accused persons and seeks to establish whether additional individuals were involved.
Separate Cases Link Latest Arrests to Wider Investigations
The NIA Manipur attack arrests involve two distinct cases rather than one combined investigation. One concerns the 2024 ambush on the former Chief Minister’s convoy, while the other concerns the 2026 IED attack in Bishnupur district.
That distinction is important because the incidents occurred at different locations and times. The convoy ambush took place in Kangpokpi district in June 2024. Meanwhile, the IED case concerns the April 2026 incident at Tronglaobi in Bishnupur district.
The NIA has nevertheless followed a similar investigative approach in both cases. Investigators are examining the alleged roles of arrested persons, their links with other suspects and the wider networks connected to the incidents.
In the convoy case, the latest arrests bring the number of accused arrested in that investigation to four. Earlier arrests had already placed other suspects before the investigative and judicial process.
Similarly, the arrest of Haokip brings the number of accused arrested in the Trongloabi IED case to two. The agency continues to investigate whether other people allegedly connected with the attack remain unidentified or at large.
Meanwhile, the courts have imposed different periods of police custody in the two cases. Singson and Haokip received eight days of police custody in the convoy case, while Thangmang Haokip received 12 days in the IED case.
Police custody allows investigators to question the accused and pursue investigative leads under judicial supervision. After custody ends, further judicial decisions will determine the subsequent stage of each case.
The NIA’s continuing investigation also means that allegations against the arrested persons have not yet been established through a final court judgment.
NIA Investigation Continues as More Suspects May Face Scrutiny
The NIA Manipur attack arrests mark another stage in investigations into serious attacks in the state. The agency has said that it is continuing efforts to establish the specific roles of the accused and trace their alleged links with other members of the respective conspiracies.
In the convoy case, investigators are examining how the alleged attack was planned and facilitated. The agency is also seeking to identify anyone else who may have participated in the incident.
The same broader approach applies to the IED case. Investigators are examining the circumstances of the attack and the alleged involvement of those already arrested.
However, the two investigations should not be treated as evidence of a single network without a formal finding from the authorities or courts. They concern separate incidents, and the available reports do not establish that the cases are directly connected.
The arrests nevertheless highlight the continuing role of the NIA in investigating major security-related cases in Manipur. The agency has taken over several cases involving violence and alleged insurgency-related activities in the state.
For the families and communities affected by the incidents, the investigations could provide further information about what happened and who was allegedly responsible. At the same time, the legal process requires investigators to establish evidence before charges can result in convictions.
Further arrests, additional charges or court proceedings could therefore follow as investigators examine evidence and alleged links. Until then, the cases remain under investigation.
The latest developments also show how investigations can continue for years after an incident. The convoy ambush occurred in 2024, yet the NIA’s investigation has produced additional arrests in September 2026.
Similarly, the Bishnupur IED investigation has progressed through multiple arrests several months after the April incident. Such developments demonstrate that investigative agencies may continue examining evidence long after an initial case registration.
Conclusion
The NIA Manipur attack arrests have added three more accused persons to two separate investigations. Jangminlun Singson and Thangjoel Haokip were arrested in connection with the June 2024 ambush on the then Chief Minister N. Biren Singh’s convoy.
Thangmang Haokip was separately arrested in connection with the April 2026 IED attack at Tronglaobi in Bishnupur district, where two children died after the incident.
The latest arrests have expanded both investigations, but neither case has reached a final conclusion. The NIA continues to examine the alleged roles of the accused, their connections and the possible involvement of other individuals.
