Days after a Hyundai i20 car exploded outside the Red Fort, killing 10 people so far, a small town called Pinangwan in Haryana’s Nuh district has come under the radar of the probe agencies, as the ammonium nitrate – suspected to have been used in the explosion – was purchased from a shop in the town.At Pinangwan, located in Mewat region, near Rajasthan’s Alwar and Bharatpur districts, farming is the major occupation, with most residents engaged in cultivating mustard, wheat and vegetables.Six shops in the town, selling fertilizers and seeds, are under the watch of security agencies and local police, said sources in the police.Story continues below this adAmong them, Aggarwal Agencies – located at the centre of Pinangwan’s main market – is the shop from which the accused purchased five to six packets of fertilizers days before the blast. It is suspected that the accused mixed these fertilizers with chemicals to make explosives.While the probe agencies on Wednesday picked up the owner of Aggarwal Agencies, officers have also taken away fertilizer samples and the shop’s DVR (digital video recorder). Sources said the agencies are trying to establish whether Aggarwal Agencies and other such shops have necessary permission or licence to sell their products.This comes after the Faridabad Police and the Jammu and Kashmir Police on Sunday recovered 358 kg of ammonium nitrate, along with 2,500 kg of bomb-making materials, from the rented accommodation of the suspects – who were employed by the Al Falah University – in Faridabad, a day before the blast near the Red Fort. Pinangwan is located at a distance of around 60 km from the Al Falah University campus.On Friday, The Indian Express visited Aggarwal Agencies only to find that it had been closed since Thursday.Story continues below this adNeighbours said the shopowner, Dinesh Kumar Aggarwal – also known as Dabbu – is engaged in the wholesale business of fertilizers and pesticides. While he lives on the top two floors of a building, his shop is located on the ground floor.“Yesterday, we heard that on Wednesday night, some police officers took Dabbu away with them. The shop has remained closed since then. I think his family members have also gone somewhere after locking their house and the shop,” said a neighbour, also a shopkeeper.Another shopkeeper said that Dinesh is one of the biggest suppliers of fertilizers in the area. “We don’t know what product he sold to (the accused), but we hear it was in a huge quantity.”Fear of coming under the radar of the security agencies is evident among the shopkeepers of the area; many fertilizer and pesticide dealers refused to speak to the media.Story continues below this adOne of the dealers, whose shop is located about 300 m from Aggarwal Agencies, said, “Koi nahi baat karega. Sab daare hue hain (No one will talk, everyone is afraid).”This shopkeeper is a sub-dealer who sources supplies from Aggarwal Agencies and sells them in the retail market to farmers.“Aggarwal Agency is a reliable and trustworthy wholesale dealer for small dealers like us. I heard it was a composition of NPK (Nitrogen, Phosphorus, and Potassium) fertilizer that he sold (to the accused). It is also used for making pesticides,” he said.“We have heard that some other wholesalers have also been picked up from other areas. But from our village, it is only Dabbu,” he added.Story continues below this adPinangwan police’s Station House Officer, Subhash Chand, told The Indian Express that “six to seven fertilizer dealers have been questioned so far”.The sarpanch’s husband at Pinangawan, Manoj Kumar, said Dinesh and his family have been involved in the business for decades. They also run a cement and construction materials’ business in Nuh city.“I want to ask one thing, how is it possible for someone to know that their product would be used in such away? I am sure that no shopkeeper from our village was involved in this conspiracy,” he added.
