Preliminary investigations being conducted into the Pune blast, which killed 8 people and injured 40 others, have revealed that the improvised explosive device used in the blast was similar to the one used in the Jaipur serial blasts.
The IED had been placed in a bag and planted at the German Bakery at Koregaon Park in Pune. It was triggered off when a waiter tried to open the bag.
The Mumbai Anti-Terrorism Squad and the Pune police, who are conducting the investigation, are trying to ascertain whether there is a particular signature style involved in the two blasts. Investigations into the Jaipur serial blasts, which claimed 60 lives, had revealed that terror outfit Indian Mujahideen, the prime suspect behind the Pune blast, had planned and carried out the terror act.
Sources told rediff.com that the nature of the IEDs and the manner in which the bombs had been packed were similar in both cases. The explosive devices were made of RDX, ammonium nitrate and metal pieces, said sources.
