Chief Metropolitan Magistrate Kaweri Baweja remanded the accused to police custody till February 4 after the special cell submitted that it needed to quiz the accused to “unravel” their specific roles in the CP blasts.

The police contended that the accused needed to be interrogated about the planning and the execution of the blasts. Saif had planted the bombs in dustbins near Regal Cinema and at the children’s park near India Gate, along with co-accused Zia-ur-Rehman and Sajid, who was killed in the Batla House encounter on September 19. Moving the remand application, the police added that Hakim had allegedly arranged ball bearings for the bombs used in the blasts.

Opposing the demand for custody the defence counsel argued that the accused had been remanded to police custody earlier, and they had already been interrogated at length at the time by the investigating agency.

The court had earlier sent all the six accused to judicial custody that ended on Monday, for interrogation in connection with their role in the blasts in Karol Bagh and Greater Kailash.
