Armed naked woman with boy tasered in WA

A naked woman armed with a knife and pushing a four-year-old boy in a trolley has been tasered by police in Western Australia's South West region.

Police say the 43-year-old woman refused repeated requests to put the knife down before she was tasered and taken to Bunbury Regional Hospital on Wednesday afternoon.

The child was not injured and arrangements have been made for his care by family members while the incident is investigated.
