Police would like to speak to a man who was seen leaving a Munster property where a 37-year-old woman was left with paralysing injuries.
The woman was found by her parents after being assaulted in her Lawson Place home some time between Tuesday July 22 and Friday July 25, police spokeswoman Susan Usher said.
She was rushed to Royal Perth Hospital suffering serious injuries, including bleeding to her brain, a loss of sight and paralysis down the left hand side of her body.
Police say a man with a shaved or bald head was seen leaving the premises.
He is described as about 40 years old, 178 centimetres tall with fair skin and a stocky build.
He was seen leaving in a blue or grey coloured sedan.
Anyone who can identify the man, or who may have seen the man or the vehicle around Lawson Place, should call Crime Stoppers on 1800 333 000.
