TWO men were allegedly taking photographs of children at Doubleview, Churchlands and Wembley Downs schools.
Acting Senior Sergeant Cris Marzo said there had been five reported incidents at secondary and primary schools in the areas and possibly more that had not been reported.
Incidents were reported on May 20 and during the week from May 16.
“We will have officers and response teams paying particular attention to these areas,” he said.
“Parents and the public should be vigilant, if you see anyone taking photos try to get a registration number or a good description.
“Parents should ensure they educate kids about stranger danger and make sure they are self-aware.”
One man was described as caucasian in a silver hatchback car and the other was described as an Asian man on a pushbike.
Police were investigating possible suspects and conducting patrols of the areas.
