IED had ammonium nitrate: Official
It was mixed with potassium perchlorate and aluminum powder
Bengaluru: The improvised explosive device (IED) used in the December 28 terror attack on Church Street was reportedly a potent mix of ammonium nitrate with another oxidant - potassium perchlorate and aluminum powder with nails and shrapnels, and was detonated using a timer device with a battery circuit of 9v battery and suggests the involvement of the five fugitive members of the banned Students’ Islamic Movement of India (SIMI), who are on the run after escaping the prison in Khandwa in Madhya Pradesh last year, said an official source.
“The explosives are similar to the May 1 train blast in Chennai and the July 10 blast in Pune, which were reportedly carried out by the fugitive gang,” he added.
The forensic examination of the IED, which killed one person and injured three others and left a 9 inch crater on the ground, has reportedly confirmed the use of these chemicals in the IED.
The timer may have got vapourised in the blast, which was certainly meant to kill and maim lives.
The Pune Anti-Terrorist Squad (ATS) was in the City to share information, forensic report and the CCTV footage of the July 10 blast in Faraskhana and Vishrambaug police stations, which are in the proximity of the famous Shrimant Dagdu Sheth Ganpati temple in Budhwar Peth.
The low intensity blast had injured five people and was reportedly the handiwork of the absconding SIMI men - Aizazuddin alias Aizaz Mohammed Azizuddin, Zakir Hussain alias Sadiq Badrul Hussain, Mehboob alias Guddu Ismail Khan, Aslam Ayub Khan and Amzad Ramzan Khan, who had fled to Odisha soon after the prison break and had later gone to Bijnor in Uttar Pradesh from where they escaped after an accidental blast.
In between they allegedly executed the May 1 train blast in Chennai, looted ' 46 lakh from a bank in Karimnagar, Telangana and planted the crude bomb on a railway track near Khanapur taluk in Belagavi district.
