The PSNI are investigating two suspicious approaches in the Craigavon area.
Last night (Thursday) a blue van stopped near young boys aged between nine and eleven.
Police say the men inside offered the children money to get in the van.
Both incidents happened in the Clonmeen area.
Police believe the 'disturbing incidents' may have been a 'sick joke'.
They're warning the men to contact them before they're found.
If you saw the van around 7:30pm on 8th September, contact the PSNI by dialling 101.
