About 11pm on Monday, October 30, two males entered a North Coogee property via an unlocked rear door while a resident was asleep in the upstairs bedroom. Once inside the property the males approached the victim and held a large knife towards his throat and threatened him several times. Police say the intruders stole the man’s wallet, mobile phone and car keys. The knife used during the incident is still missing. Anyone with information on the whereabouts of the knife should contact Fremantle Detectives on 9431 1200.
