New Delhi: The Gujarat Police’s Anti-Terrorism Squad (ATS) has allegedly recovered four kilograms of castor-bean mash from a Hyderabad doctor arrested over suspected terror links on 7 November.

The ATS suspects that the doctor had procured the castor-bean mash to extract the deadly poison, ricin. He is also alleged to have surveyed crowded food markets in Delhi and Ahmedabad as sites for potential attacks.
