In a major breakthrough in the NIA probe into the deadly Red Fort blast that killed 13, it has been revealed that the suicide attacker Umar un Nabi may have acted as a "shoe bomber".
A metal trigger attached to Umar's shoe and his blown-off ankle are key evidences to the latest finding, according to reports.
Earlier, it was revealed that triacetone triperoxide (TATP), also known as acetone peroxide, was found inside the Hyundai i20 that blew up in the November 10 blast. The chemical is infamously nicknamed 'Mother of Satan' due to its high risk of accidental detonation. A minor friction, shock, heat or static electricity can detonate this white crystalline powder.
The Forensic Forensic Science Laboratory has reportedly found traces of 'Mother of Satan' in the shoe as well as on the right front tyre of the i20. The Jaish operatives reportedly used a combination of TATP and ammonium nitrate for the blast. A metal-like trigger inside the shoe is said to have activated the explosion, as per the probe.
According to officials, the detonation method used by Umar may have been inspired by the notorious "shoe bomber", Richard Reid, who had in December 2001 boarded a Miami-bound American Airlines flight from Paris, concealing 'Mother of Satan' in his shoes. However, his attempt to trigger an explosion failed.
