A package containing white powder, later identified as explosive, was found inside the Uttar Pradesh assembly on Thursday. The package, which weighed about 150 g, was found under the seat of Samajwadi Party member MLA Mano Pandey.
The forensic laboratory has identified the powdered substance as an explosive PETN plastic (pentaerythritol tetranitrate). Addressing the Friday meeting at the meeting, Chief Minister Yogi Adityanath said: “This is PETN is a dangerous substance is to reveal who is behind this police check should be performed on all … security agents.”
Pentrite or pentaerythritol tetranitrate is one of the most dangerous plastic explosives. The substance is available on the black market and belongs to the same family as nitroglycerin. Militant groups prefer because it can be easily detected because of their colorless crystals.
Most explosives detectors use metal detectors, but PETN can be hidden in a sealed container or electrical equipment and can easily overcome security controls.
According to a 2010 report in The Guardian, several countries have strong restrictions on buying PETN that can be purchased in powder or thin plastic sheets.
The substance is used legally by the military and in mining, where it is used in detonators for chains and detonation mines. PETN can be mixed with other chemicals to form Semtex.
PETN is not doing it alone. The explosive needs a secondary detonation mechanism for the generation of heat or a shockwave, which can detonate the explosive.
James Crippin, a Colorado explosives expert, told CBS in an interview in 2009 that the substance is stable and safe to handle but requires a primary explosive to detonate. The device, according to The Guardian, is based primarily on a plastic lid to disable it.
The PETN substance was used in the number of bomb incidents in recent years, some of which have not materialized. In 1983, Charles the Jackal used PETN device in 1983 for the attack on the house of France, the French cultural center in Berlin.
In 2001 “bomber shoe” Richard Reid attempted to blow up an American Airlines flight on his way to Miami. Reid tried to put the explosive in the fire, but he did not.
In 2009, Umar Farouk Abdulmutallab attempted to detonate a concealed PETN explosive in his underwear in a failed attack on a flight from Northwest Airlines to Detroit. In 2010, Abdullah Hassan al-Asiri tried to assassinate the deputy minister of the Interior of Saudi Arabia with a Pentrite bomb hidden in his body.
It was also used in 2009 under the Christmas bombing in 2009 and in 2010, an airplane bomb in London and Dubai, a Times Economic Times reported.
In addition to PETN explosive reports worldwide, it is believed that the substance was used in 2011, the Delhi High Court explosion, in which at least 17 people died.
“Preliminary investigations reveal that the service was created. The evidence found by the forensic team indicates the possible use of nitrate-based explosives with PETN,” said British President Bansal, Secretary of Homeland Security after the explosions.
