PRAYAGRAJ, March 28 -- Investigation reports regarding the Chandapur cold storage collapse owned by former minister Ansar Ahmed are gradually being submitted to the administration's inquiry team. The fire department confirmed that the cold storage facility had a valid no objection certificate (NOC). Meanwhile, an expert team from Indian Farmers Fertiliser Cooperative Limited (Iffco), after conducting an inspection, concluded that although ammonia may have leaked, the ammonia tank did not explode. The inquiry committee, however, continues to conduct its own independent assessment. The Prayagraj Development Authority (PDA) is yet to submit its report, after which the committee will prepare a comprehensive final report for the district magistrate. According to Vinita Singh, ADM, (finance and revenue), heading the inquiry committee, based on the fire department and Iffco findings, the ammonia pipeline joints were found intact and the adjacent generator room showed no signs of structural damage, some of the factors that indicated that the tank did not explode. However, she clarified that the committee will continue examining this aspect until the PDA's report is received. Once all reports are compiled, a detailed final report will be submitted to the DM. The cold storage facility had collapsed on Monday, killing four people and injuring more than a dozen others, prompting DM Manish Kumar Verma to form an inquiry committee to investigate the incident. Meanwhile, police arrested two more accused in connection with the accident at Adarsh Cold Storage, located at Chandapur Morhu under the Phaphamau police station limits. Mohammad Usman and Mohammad Irfan, both residents of Chandapur, were taken into custody on Friday near the Phaphamau railway station. A case had already been registered against them, and four other named accused had earlier been arrested and sent to jail....
