Gardaí in Tramore are investigating two suspicious approaches on children in the town this week.
Yesterday, sixth class students were orienteering when three of them were approached by a man who asked them to get into his car.
On Wednesday, a man approached a teenage boy on a bus from Tramore to Waterford.
Officers are also investigating an alleged sexual harrassment on Tramore Beach last week.
A woman was approached by a man while she was with her children.
Gardaí don't believe the incidents are connected.
