A Perth grandmother has been left terrified after she woke up to a man hacking at her house with a chainsaw.
Security vision captured the hooded man taking the weapon to the front door in Yanchep just before 6am on Thursday.
Bev Miller was asleep with her six-year-old granddaughter inside when the man started smashing the door before moving on to the window.
"I screamed through the window, which was a bit stupid, and he came at me with the chainsaw," Ms Miller said.
"He smashed one side and I ran inside and closed the doors and everything."
Ms Miller said the chainsaw missed hitting her face by centimetres.
