The Gujarat Police’s Anti-Terrorism Squad (ATS) on 8 November 2025 arrested Ahmed Mohiyuddin Saiyed, a doctor from Hyderabad (Telangana), along with firearms and nearly 4 kg of castor-bean mash, which is used to extract ricin, a bio-toxin, at Adalaj toll plaza on Ahmedabad–Mehsana Road in Gandhinagar. His call records led to the arrest of two Uttar Pradesh residents, Azad Suleman Sheikh and Mohammad Saleem Khan, in Banaskantha, Gujarat.

As the investigations into the Las Vegas Ricin poisoning continue with the Centers for Disease Control issuing a health advisory already, the mystery over two vials of poison found in the Von Bergendorff’s Motel room still haunts Police, FBI and U.S. Homeland Security agents. Police claimed to have found guns, "anarchist-type" fiction (with the ricin section highlighted), and castor beans from Bergendorff’s room, which has been under medical supervision since mid-February.
