'Mother of Satan' explosive used in deadly Delhi Red Fort blast? Investigators probe terror module

Unlike conventional explosives such as ammonium nitrate, TATP can detonate from heat, friction, or pressure without a detonator, making it highly unstable.

The explosion, which killed 13 people and injured nearly two dozen, occurred when Umar Mohammad, a doctor allegedly linked to the Pakistan-based Jaish-e-Mohammed terror group, drove a Hyundai i20 into the crowded Chandni Chowk area.

Investigators are examining residue from the site to confirm TATP’s use, as the blast’s intensity and shockwave patterns are consistent with the explosive.

Police are probing how Umar sourced the chemicals, whether others were involved in preparing the device, and how the explosive remained stable inside the car for hours before detonating.

Three of Umar’s colleagues—Shaheen Saeed, Muzammil Shakeel, and Adil Rather, all doctors at Faridabad’s Al Falah University—have been arrested in connection with the attack.

Authorities recovered nearly 3,000 kg of explosives and bomb-making materials from the suspects’ properties.

A rifle and ammunition were also found in Saeed’s car, with her passport verification suggesting possible plans to flee the country.

Investigators are now reviewing digital trails, movement logs, and communications to map the full extent of the terror module’s activities, amid concerns that the group may have planned serial attacks across the National Capital Region.
