A day after the twin explosions at the Jama Masjid, Delhi police sleuths were piecing together evidence from the blast site to trace the perpetrators of the attack. Forensic experts were examining samples collected from the site of the blasts, which left 13 people injured.
"The explosives used in the blast were of a very crude nature," police sources said, adding that they were examining all angles in the investigation.
Delhi police Commissioner K K Paul met Union Home Secretary V K Duggal Saturday morning to apprise him about the situation in the aftermath of the blasts.
Meanwhile, security at the Jama Masjid was tightened and metal detectors were in place at its three gates in view of the blasts. Delhi Police and Central Reserve Police Force personnel were deployed in large numbers at the 17th century mosque.
Preliminary investigations revealed that potassium chlorate and sulphuric acid were used to trigger the explosion. Nuts and bolts were added to the mixture to cause injury.
"The intention behind the explosions was to create panic in the city," police officials said, adding that Delhi has been the target of terror attacks for quite some time now and as many as 51 terrorists have been arrested in the national capital since January 2005.
A high alert has been sounded in the capital and police officials heightened vigil at religious places and vital installations in wake of the twin explosions.
