A Dunedin doctor accused of killing a teenage girl has applied for bail for the fourth time. Venod Skantha (31) has pleaded not guilty to the murder of 16-year-old Amber-Rose Rush, who was found dead in her Corstorphine home on February 2 last year. Skantha has been denied bail and electronically monitored bail by the High Court and the Court of Appeal three times in the past. A fresh application for bail can be made if there is a material change in circumstances. Justice Gerald Nation heard the bail bid in the High Court at Dunedin yesterday and reserved his judgement.
