Children as young as ten-years-old are playing on the flyover bridge at Belfast Road in Bangor.
Police say they have received reports that several very young children were playing on the bridge.
And according to the report, one child was standing on the wrong side of the railings.
Worryingly, police say the children looked as young as ten.
Police are issuing a warning to parents to make sure they know where their children are at all times.
