In a major development to the investigation into the Tamanna murder case, police filed a supplementary charge sheet against the remaining accused, bringing all 24 persons named in the FIR under the ambit of prosecution.
With the latest filing, all the accused have now been arrested during the investigation; 23 remain in judicial custody and one is out on bail, paving the way for the commencement of trial.
Tamanna, a nine-year-old girl from Kaliganj in Nadia district, was brutally murdered on 23 June 2025, triggering widespread public outrage and protests across the district. She was killed by a crude bomb thrown during a premature victory rally of the Trinamool Congress during the counting of the Kaliganj assembly byelection.
The case had drawn significant political attention, with demands for swift investigation and exemplary punishment for those involved.
The supplementary charge sheet (No. 470/26), dated 21 July 2026, was submitted before the Chief Judicial Magistrate (CJM), Krishnagar, following the completion of further investigation in Kaliganj Police Station Case No. 534/25, registered on 23 June 2025.
Atul V, Superintendent of Police said the case was initially registered under various provisions of the Bharatiya Nyaya Sanhita (BNS) and Sections 3 and 4 of the Explosive Substances Act. During the earlier phase of the investigation, a charge sheet had been filed against 13 of the 24 FIR-named accused.
Of them, 11 were arrested, while warrants of arrest had been issued against two absconding accused. One of the arrested accused later secured bail from the Calcutta High Court.
During further investigation, police arrested the remaining 11 FIR-named accused who had not been chargesheeted earlier, along with the two accused against whom warrants had already been issued. Consequently, all 24 persons named in the FIR have now been apprehended.
According to the police, the supplementary charge sheet has been filed under Sections 190, 191(2), 191(3), 118(2), 109, 103, 305, 61(2) and 3(5) of the Bharatiya Nyaya Sanhita, Sections 3 and 4 of the Explosive Substances Act, and Section 25 of the Arms Act.
The state government has appointed senior advocate Bivas Chatterjee as the Special Public Prosecutor to conduct the trial in the case.
With the supplementary charge sheet filed, investigators have completed the prosecution’s case against all the accused, marking the end of the investigation and clearing the way for the trial in one of Nadia’s most high-profile criminal cases.
