The former chief minister Jayalalithaa was treated on the second floor of the Apollo Hospitals unit.In March this year, Apollo Group Chairman Prathap Reddy had told reporters that CCTV Cameras were not available as they were switched off.The Arumughaswamy Commission had written to the hospital group seeking submission of video footages related to the period AIADMK J Jayalalithaa had stayed in the Greams Road, Chennai unit of the hospital group between September and December 2016. Appearing before the Commission, Subbiah Viswanathan, Chief Operating Officer of Apollo, had submitted that certain government officials, he was told, had requested that the cameras be switched off.Sources within the Commission believed that the cameras could have recorded movement of other people on corridors from vantage points, leaving alone the fact that the equipment were switched off when Jayalalithaa was to be moved around in the hospital. However, Apollo Hospitals had said in a letter that the data servers are overwritten once in about a month, rendering it incapable of producing any footage recorded two yeats ago.The Arumughaswamy Commission, according to people aware of developments, has sought another a extension of three months to finish compelting inquiries. It was supposed to file its report by October 24.
