New Delhi: In its final post-blast investigation report, the National Security Guard (NSG) has said that the IED found in Delhi's Ghazipur flower market last week had ammonium nitrate and RDX as its components and a timer was attached to it.


A PTI report said the NSG submitted its report to the Delhi Police on Monday.


"The IED contained ammonium nitrate, RDX, a 9-volt battery, iron pieces that could act as shrapnel during an explosion and had a timer device attached to it," the report said.

The RDX was used as the core explosive in the IED but it did not blow off due to a "glitch" in the circuit, the investigation report said.


After the IED, weighing three kg, was found in an unattended bag in the busy flower market of Ghazipur on January 14, a team of NSG's bomb disposal squad and officials from Delhi Police's anti-terror unit Special Cell weer rushed to the spot.


NSG had sent experts from its National Bomb Data Centre (NBDC) based in Haryana's Manesar to defuse the IED. The NSG conducted a controlled explosion to neutralise the explosive.


The bomb was placed at the main gate of the flower market. A pit was dug at the flower market campus and the IED was blown under a "controlled explosion" procedure by the NSG personnel.


The Delhi Police is yet to make any headway in the investigation in the case. According to police officials, no suspect has been identified so far, PTI reported.


The incident happened days before the January 26 Republic Day celebrations. The security apparatus in the national capital has been put on a high alert.
