New Delhi: Delhi govt’s Anti-Corruption Branch (ACB) Friday opposed interim bail to former Director General of Health Services (DGHS) Vatsala Aggarwal and co-accused Dr Vinod Kumar Ranga in the alleged Rs 700-crore medical procurement scam, alleging they colluded to concentrate decision-making powers in their hands to favour bidders like alleged mastermind Rajeev Kumar Rangeela, who lacked required experience and turnover.During arguments on Ranga’s bail plea, the prosecution alleged that the duo bypassed two middle-level officers and assumed powers to take key decisions on their own. It further stated that Ranga kept crucial procurement files in his personal custody, which were still missing, and that releasing him on interim bail could adversely affect the investigation.Special judge Vidya Prakash, who heard the bail pleas of the duo, reserved the order for Monday.Aggarwal, 61, sought interim bail citing hypertension, bronchitis, asthma, diabetes and breathing difficulties. Her counsel argued that she was under treatment and that continued incarceration was unjustified on medical grounds. He submitted that at this stage, the court was required to consider whether continued custody was conducive to her health, rather than determine her guilt.“Everyone has the right to good treatment, no matter how serious the offence,” the counsel submitted, offering to follow stringent conditions of prosecution, including monitoring Aggarwal’s movements through the investigating officer. The counsel said that she was suspended, had no access to the office and had not interfered with the investigation.Opposing the bail plea, the prosecution said Aggarwal was a senior officer and her custody was necessitated by the seriousness of the alleged scam. “It is not a pleasure for the State to keep its seniormost officer in jail. We were compelled to do so,” it submitted.On her health, the prosecution said Aggarwal had been examined six times and was being “taken care of very well”, with stable vital signs and no medical urgency. It also claimed that she was involved in manipulation of files and was “the last point” in the alleged chain of irregularities.The arrests were made after allegations surfaced of inflated procurement of medicines, linen and medical equipment by the Central Procurement Agency under the DGHS, including ORS packets priced at Rs 15 against an actual cost near Rs 2.50, and hospital bedsheets bought for Rs 450 instead of Rs 150.
