The Special Investigation Team (SIT) police filed the charge-sheet in the pipe bomb case in the Judicial Magistrate court, Tirumangalam.
In October 2011, hours before Bharatiya Janata Party leader L.K. Advani was to leave Madurai on a southern tour and reach Kerala by road, some miscreants had planted explosives under a culvert at Alampatti near Tirumangalam in Madurai district. Bomb Detection and Disposal Squad removed it from the spot and defused the explosives.
Within a week, the case was transferred to the SIT police. Cases under Indian Explosives Act and under 120 b (conspiracy), 307 (attempt to murder) among others were registered.
Taking up the investigations, a team led by Deputy Superintendent of Police Karthikeyan zeroed in on the suspects and arrested three persons — Ismath, Abdullah and, Hakeem —and detained them in prison. Based on their confession, the police named ‘Police’ Fakrudeen, Jalal Malik, and Mohammed Hanifa in the case as key accused and were on the look out for them.
Under such circumstances, based on a sanction from Madurai Collector, the SIT police filed the charge-sheet in the JM court, which was taken on file on November 27, police said.
