The Faridabad police have detained two persons, one from Aligarh whose cell phone was used to make calls to media organizations after the blast in Mehrauli in south Delhi on September 27 that killed two and injured 24 people. Second person is a businessman from Faridabad who sold the sim card. The police claim that they have new definitive leads on the Mehrauli attack. Police have connected this blast to three similar blasts in south Delhi earlier this year. The three blasts had occurred at Lado Sarai, IIT crossing and at Green Park area, but were then considered as an act of mischief and never considered as an act of terror. It is being said that the nature of explosive was similar to the ones in Mehrauli yesterday.Investigators then had visited Jalpaiguri and Siliguri in West Bengal and questioned a few people regarding this including one person known as Jalaluddin.Besides these three blasts, investigators are now finding similarities between six more explosions of similar nature from 2001 to 2008 that took place in Delhi. Most blasts have remained unsolved. Among the mysterious explosions that took place in Mehrauli, one was near Indian Institute of Technology on January 16 in which one person was injured. A fortnight later, two similar blasts were reported from Malaviya Nagar locality. Massive manhunt for Mehrauli bombersMeanwhile, Delhi police have launched a massive manhunt for the two men who dropped the bomb in crowded Mehrauli market and launched extensive checking across the capital. The two men, believed to be aged around 30-32 years, riding a black motorcycle with Delhi registration number were responsible for the explosion in which a boy was killed and 18 other people injured. "The two well-built suspects wear in black dress, were wearing black helmets and riding a black Bajaj Pulsar. So it has not been possible for the eye witnesses to identify them," Joint Commissioner of Police (Southern Range) Ajay Kashyap said after the blast. The person riding in pillion dropped the packet containing tiffin in which the explosive was hidden near an electronic shop in the Mehrauli market. A child picked up the packet and wanted to return it to the motorcycle riders but it exploded killing him. Three persons, including a couple, saw the entire episode and are being questioned. Ammonium nitrate used in low intensity blastOfficials said the ingredients of Mehrauli bomb was ammonium nitrate in a small quantity along with sulphur and potassium. The bomb was loosely packed and contained one-and-a-half inch nails while sulphur was used to create dark smoke.Potassium was used as the triggering mechanism as this material burns due to friction and contact with air. The packing of explosive was very loose thus making it a low-intensity explosion.Ammonium Nitrate was used in the five serial blasts that shook the national capital on September 13, leaving 24 people dead and many others injured.In order to restrict sale of Ammonium Nitrate, used extensively by terror groups to strike in various parts of the country, the government had "in-principle" approved for amendment of the Explosives Substances Act to include it.The chemical was believed to have been used in recent series of explosions in Bangalore, Ahmedabad and Delhi and in many earlier blasts including the serial train blasts in Mumbai, Malegaon and Mecca Masjid blasts. Theories on blastThe investigators are seeking answers to why such a haphazard attempt was made two week after the well coordinated attack. Several theories are being explored.
Theory 1: Investigators believe that terror modules retaliated under pressure after recent crackdown by police forces in various states like Delhi, Gujarat, Rajasthan, Karnataka and Mumbai.
Theory 2: Terror modules may not have planned an elaborate plan to target, but want to perpetuate fear and panic by incidents like throwing explosive device.
Theory 3: Some elements of terror modules could be warning security with yesterday's blasts that they were still active, daring them with their dangerous intentions.
