The National Investigation Agency (NIA) has filed a chargesheet against three individuals in connection with a suspected bioterrorism conspiracy linked to the Islamic State (ISIS). The case involves an alleged plan for mass poisoning using the deadly toxin ricin. The chargesheet was submitted on May 6, 2026, marking a significant step in the investigation.
Accused and Charges
The main accused, Hyderabad-based Dr Syed Ahmed Mohiuddin, along with Azad and Mohammad Suhel from Uttar Pradesh, have been charged under the Unlawful Activities (Prevention) Act (UAPA), the Bharatiya Nyaya Sanhita, and the Arms Act. According to investigators, the accused were allegedly guided by foreign-based ISIS handlers and were involved in recruitment, fund transfers, weapons handling, and reconnaissance activities.
Details of the Conspiracy
The NIA claims that Dr Mohiuddin had attempted to prepare ricin from castor seeds in a clandestine setup. Ricin is a highly toxic protein that can be lethal in small doses. The co-accused, Azad and Mohammad Suhel, are alleged to have handled logistics and coordination for the plot. The group was reportedly planning to use the toxin for mass poisoning attacks.
Investigation Origins and Progress
The case originated with the Gujarat Anti-Terrorism Squad (ATS) arrest in November 2025. The NIA took over the investigation in January 2026. The probe is ongoing to trace wider networks and foreign links connected to the alleged conspiracy. Authorities are working to identify any additional individuals or cells that may be involved.
The filing of the chargesheet underscores the seriousness of the threat posed by ISIS-inspired bioterrorism. The NIA continues to investigate the case to ensure all perpetrators are brought to justice.
