A WA police officer has been stood down from duty after he was charged with assaulting his child. In his first appearance at the Perth Magistrates Court on Monday morning, Cameron Douglas Smith, 28, requested the matter be adjourned in order to seek further legal advice. Detectives from the child abuse squad charged Mr Smith, who serves in the Perth metropolitan district, with unlawful assault and thereby did bodily harm with circumstances of aggravation on November 24. It is alleged that Mr Smith injured his son in August, in Nedlands, which resulted in his child needing medical treatment. A WA Police spokeswoman said the officer was stood down immediately. Mr Smith has been released on bail with a list of conditions including staying 20m away from high schools, primary schools and daycare centres. He is due back before the court on January 15.
