A private medical company uncovered a fake doctor accused of evading NSW health authorities for more than a decade while treating patients at four Sydney and Central Coast hospitals. NSW Health Minister Brad Hazzard has called for a jail term for Indian man Shyam Acharya, who allegedly stole the name and medical qualifications of Sarang Chitale to enter Australia and then work at Manly, Hornsby, Wyong and Gosford hospitals between 2003 and 2014.
