An investigation is being carried out after a raid on a cash-in-transit van at Killiney Shopping Centre at 10am this morning.
A lone raider threatened staff with what is believed to be a handgun.
He fled the scene with an undisclosed sum of money.
A red Peugot van (97 WX 1591) used by the raider was found abandoned in the church car park in nearby Sallynoggin.
Gardaí said there was water dripping from the back door of the van when it was found.
They are keen to speak to anyone who had seen the van in the shopping centre car park behind the Euro Spar.
Gardaí in Cabinteely can be contacted on 01-6665400.
