PETN link in Red Fort blast intensifies security investigation

Investigators probing the explosion near Delhi’s Red Fort are focusing on the suspected use of PETN, a powerful military-grade explosive rarely seen outside high-risk terror operations. The detection of PETN traces has heightened urgency within national security agencies, which are now examining potential supply chains and trafficking routes behind the blast.

Forensic indicators of PETN use

Initial laboratory assessments suggest the presence of pentaerythritol tetranitrate, a high-velocity nitrate compound often associated with sophisticated explosive devices. Its combination with ammonium nitrate points to a technically assembled charge. PETN’s sensitivity to heat and friction, and its ability to integrate easily into plastic explosives, make it extremely destructive in compact quantities.

Security concerns around procurement

The suspected use of PETN has raised sharp questions about access to restricted chemicals. PETN is not commercially available in India and is manufactured only under strict licensing for defence purposes. Past seizures in regions such as Jammu and Kashmir and Kerala indicate the existence of covert procurement channels. Agencies are investigating whether a similar network enabled the movement of PETN into the capital.

Tracing supply routes and networks

Detecting PETN is challenging when used in small doses or blended with other materials, adding complexity to the investigation. Authorities are analysing surveillance footage, reconstructing the blast sequence and coordinating with national agencies familiar with illicit explosive trafficking. Previous high-profile cases, including the 2011 Delhi High Court blast, also involved PETN, increasing concern over its latest reappearance.

Exam Oriented Facts

• PETN is a restricted military-grade explosive with high detonation velocity.
• It is manufactured only by licensed defence suppliers in India.
• Past terror cases involving PETN include the 2011 Delhi High Court blast.
• Detection becomes difficult when PETN is mixed with other compounds.

Current investigative priorities

Investigators are pursuing multiple leads involving forensic analysis, chemical sourcing patterns, and potential cross-border or domestic trafficking channels. Laboratory confirmation of the explosive composition will determine the next phase of the probe, including the identification of suppliers and possible links to organised networks believed to be behind the Red Fort blast.
