Hamilton police say reports in the east end and on the mountain of girls being approached by a man in a car are not likely related.
Three girls in east Hamilton reported being approached while walking to or from school last Thursday and Friday.
Earlier in the week, there were similar incidents involving two girls on the mountain.
Police say the vehicles used in the two areas were different.
In the east Hamilton cases, the vehicle was a blue minivan with tinted windows.
On the mountain, it was a dark coloured sedan.
