A 92-year-old woman with dementia had a teddy bear thrown in her face and her legs dropped onto a bed railing by two carers at a Perth aged care facility, a court has been told. Luz Ando Freeman and Glenda Lua are on trial in the Perth Magistrates Court charged with repeatedly assaulting Jean Robins at Morrison Lodge in Midland between September 20 and October 3, 2016. The alleged incidents were captured by a covert camera Ms Robins’s son had installed in her room after she broke her leg in a fall, to try to work out why she kept falling from her bed. Her physical and mental condition had deteriorated after she broke her femur in June 2016. Prosecutor Nicholas Van Hattem told the court Ms Robins was “difficult to care for”, but Ms Freeman and Ms Lua’s use of “excessive force” was not justified, and caused “unnecessary pain and discomfort” to the elderly woman. Ms Freeman is facing seven counts of aggravated common assault and Ms Lua has been charged with five counts. The trial has been set down for four days.
