Lucknow, Sep 5: The 150 gram of white powder that was recovered in the Uttar Pradesh Assembly on July 12 was just Silicon Dioxide and not PETN (pentaerythritol tetranitrate), a report by National Investigation Agency said. The UP government on Monday suspended the Director of the Forensic Science Laboratory (FSL) for giving a misleading information on the white powdered substance, on the basis of which the state had concluded that the substance was explosive.

“The Hyderabad CFSL, in its report, informed us that neither the substance was PETN nor any other explosive,” said a senior NIA official, reported TOI. The agency is now expected to file a closure report on the same.

In the initial report, Director of FSL Shiv Bihari Upadhyay had said that the substance was highly explosive pentaerythritol tetranitrate (PETN). The probe was then handed over to the National Investigation Agency which found that the substance was just harmless quartz or silica.

His suspension was recommended for July 22 when DG (Technical Services) Mahinder Modi and UP DGP Sulkhan Singh exchanged information on the substance which stated that Upadhyay prepared a wrong and misleading report despite knowing that the kit it was tested on had expired in 2016.

The two officers also blamed Upadhyay for not disclosing the fact that he had sent the samples to FSL Agra. “Director General of the Vigilance Department, Hitesh Awasthy, would conduct an inquiry into Upadhyay’s role in the episode,” said Principal Secretary, Home, Arvind Kumar confirmed. (Also Read Not Even Sniffer Dogs Can Detect PETN, All You Need to Know About Deadly Explosive)

On the initial report, the Yogi Adityanath govt had sent a report to the Union Home Ministry saying that the 150 g of powder wrapped in paper was PETN.

“This is PETN, this is a dangerous substance. It will be revealed who is behind this. Police verification should be conducted of every security personnel,” Adityanath had then said.
