A Garda manhunt is under way for a masked raider armed with a lead pipe who stole around €50,000 from a cash-in-transit van.
The daylight robbery happ-ened in north Dublin as the cash van made a delivery to a bank that had a similar sum stolen in a previous raid.
Detectives are continuing to hunt for the thug, and are investigating the possibility that he may have been helped by at least one other man waiting nearby.
The robbery happened at around 2.40pm on Thursday on Main Street, Finglas.
A security van was making a delivery to the Permanent TSB branch when the raider struck.
He threatened security workers with what was described by witnesses as a lead pipe before demanding the contents of the cash box.
The terrified transit worker handed over the box, which contained around €50,000, before the raider fled the scene.
Gardai are appealing for anyone with information to contact them.
No arrests have yet been made and efforts are being made to identify a number of suspects.
A source told the Herald that two men may have been involved in the robbery, and that the second thief was also wearing a balaclava.
"A male approached the cash-in-transit employee while armed with a pipe-like weapon and demanded the cash box be handed over," a garda spokesman said.
"The male left the scene with the cash box in a vehicle which was later found burnt-out.
"A large amount of cash was stolen in the incident. No injuries were sustained and investigations are ongoing."
In April 2016, an armed raider approached security workers and threatened them with a shotgun before demanding cash outside the same bank.
He then made off with around €50,000 in a blue Ford Transit Connect, which was later found abandoned in the Glasnevin area.
It is not yet known if there is any connection between that raid and the robbery last Thursday.
