Reacting to the allegations of the Arumughaswamy committee after the panel called for an investigation against Sasikala, among three others, the expelled AIADMK leader said "I deny all the allegations levelled against me in the report".
Her return to Tamil Nadu is being keenly watched as it comes at a time when the assembly elections in the state are likely to be held in the next few months.
Sasikala was in prison since February 2017 along with Ilavarasi and late Jayalalithaa's foster son V N Sudhakaran in connection with the Rs 66 crore disproportionate assets case.
According to the hospital sources, as soon as she was admitted to hospital, authorities conducted a Rapid Antigen Test on her, which has come back negative for Covid-19.
