An Australian police officer who Tasered 95-year-old great-grandmother Clare Nowland in her care home has been found guilty of manslaughter.

Senior Constable Kristian White tasered 95-year-old Clare Nowland, but the decision to find him guilty of manslaughter was whether or not his actions were reasonably necessary.

A police officer may be taken into custody a day after he was found guilty of unlawfully killing a 95-year-old woman with his service Taser in a nursing home.
