On Thursday, a student told her mother a man in a four-wheel-drive station wagon had spoken to her at the Banksia Grove school, the mother then reported it to the school principal.
The following day another student told the school gardener she had also been approached, this time by a man in a dark sedan.
Wanneroo police officer-in-charge Chris Ruck said police would heavily patrol the area.
‘We’re taking it seriously ” we’ve got patrols up there, detectives and uniformed staff patrolling the Neerabup Primary School area,’ he said. ‘Do what parents should do: Be mindful, be cautious, make sure they (students) get to school and they’re aware not to talk to strangers.
‘If they do feel threatened, (they should) run to school or to a responsible adult they know.’
Principal David Hall said there was an assembly for years 1 to 7 to discuss stranger danger, with another meeting for parents of kindergarten and pre-primary children.
‘On the afternoons of two alleged events we sent home a letter with each child with information to get parents to think about stranger danger,’ Mr Hall said. ‘We’re very pleased in both cases the students knew what to do and not to respond to any approach.’
