Three persons with alleged "ideological leaning" towards the banned JeM were arrested in New Delhi for planning terror strikes in different parts of the national capital.
The three were transferred for their trial in the shoe baron Partha Pratim Roy Burman abduction case, Inspector General (Prisons) Joydeb Chakraborty said.
Dubai-based don Aftab Ansari, the main accused, was convicted for murder, conspiracy and waging war against the country.
Kondhwa police station Inspector Varsharani Patil said, "We have registered a case against the three co-owners under sections 304 (causing death by negligence), 341 (punishment for wrongful restraint), 342 (wrongful confinement) and relevant sections of Mumbai Municipal Corporation Act and arrested them."
13 persons were picked up by the Special Cell after a late night operation on Tuesday. Of them, three -- Sajid, Sameer Ahmed, and Shakir Ansari -- have been arrested, four let off and six are still being questioned by the investigators.
