Officers from the Regional Investigation Unit are calling for public assistance in their investigation into two robberies. At 9.30pm on Tuesday 4 December 2012 a male person entered the Beaconsfield Newsagency and Mini Mart in South Street, White Gum Valley. He brandished a knife and demanded the female attendant open the till. Once the till was opened he removed a quantity of cash and ran from the store. In the second instance, it is believed that he entered the newsagency in the Hilton Plaza Shopping Centre at 9.00 am on Wednesday 5 December 2012. He approached the male staff member whilst brandishing a knife and demanded he open the till. The victim armed himself with an iron bar from behind the counter and the offender ran off. The man is described as being in his 40s, tanned complexion, slim build, 162 to 172 cm tall, brown hair, with a beard. In the first instance he was wearing blue jeans and a green and white checked shirt. On that occasion he was in company with a woman. Both can be seen in the attached photos.
