At a time when a go ahead was given for a blast, the explosives was collected from Karnataka and transported to city where the blasts were to take place.
The entire stockpile of explosives would be first delivered at either Mangalore or Kundapur in Karnataka.
It would be stocked up around 20 days before the blasts. A team of the Indian Mujahideen would then pick up the explosives and transport it to the target city ten days prior to the blasts, the Maharashtra ATS which has been questioning ZainulAbdeen has learnt.
ZainulAbdeen was arrested by the Maharashtra ATS two days back. He was detained in Saudi Arabia following a complaint by India and later sent to India where he was formally arrested.
Karnataka the stock house:
For the Indian Mujahideen, Karnataka was the stock house for the explosives. The first ever pile of explosives that were used by the Indian Mujahideen was from Karnataka.
They had managed to source ammonium nitrate in large quantities which were later used for the blasts.
Waqas a Pakistani national who was part of the Indian Mujahideen was tasked with the job of delivering the explosives. He would meet with the operatives either at Mangalore or Kundapur. These locations were chosen as the IM had created safe houses.
Moreover the ammonium nitrate which was a constant feature in the Indian Mujahideen bombs was sourced from a quarry in Kundapur.
Waqas was tasked with delivering the rest of the materials used to prepare the bombs such as the IEDs. The material would be stocked up in a safe house.
Once Yasin Bhatkal who was the chief of the IM would instruct the operatives, the explosives would be transported to the target city, Abdeen also told his interrogators in Mumbai.
