KEWDALE POLICE are searching for a man who threatened a shop attendant with a knife and robbed the store in Kewdale. At about 9.40pm on Friday, March 18, a man entered a service station on Orrong Road. The man walked up to the counter, produced a knife and a plastic bag and demanded the attendant fill the bag with money. The attendant complied with the request and handed the bag back to the man. As the man walked out, he saw a sunglasses stand, chose a pair and walked out and away from the store. Police have released a CCTV image of a man they believe can assist with inquiries. He is described as being tan skinned, 35-40 years of age with a thin to medium build. He was about 180-185cm tall with short dark hair and was wearing a blue polo shirt with dark-coloured shorts. He was also carrying a backpack. If you know the identity of this person or have any information, make a report online or call Crime Stopper on 1800 333 000.
