A cleaner accused of unleashing a vicious attack on her 92-year-old client after claiming she was threatened with a cane and a knife has been refused bail in Sydney. Indonesian citizen Hanny Papanicolaou, 35, has been charged with attempted murder and wounding with intent to cause grievous bodily harm after arriving unannounced at her elderly client’s home in Ashbury on January 2. Her barrister James Trevallion made a bail application in Burwood Local Court on Wednesday, submitting the 35-year-old acted in self defence. But magistrate Louise McManus refused it on the basis that she wasn’t satisfied any conditions would mitigate the risk Papanicolaou poses to her alleged victim and community, and the possibility of interference with witnesses. The matter was adjourned to March 6.
