Bungling raiders were forced to drop a bag of cash and a handgun on the ground during a cash van robbery in Dublin's Cork Street early this morning.
One masked raider was also arrested at the scene.
The drama unfolded at 7.40am when a crew from G4S security were working from a truck they had parked opposite the Lidl store on the busy road in the south city.
The gang struck and threatened the cash-in-transit workers with a gun, and assaulted one of them.
It was unclear early this morning what unfolded as the robbery progressed, but the raiders appear to have dropped a green skip-bag which they had loaded rolls of coins into, as well as the handgun, on the footpath beside a tree.
One man in his 30's was arrested at the scene but the remainder of the group managed to escape.
A van was found on fire a short distance away in Dolphins Barn immediately afterwards, leading gardai to believe that the gang panicked and left one of their members behind as they tried to escape.
A member of the cash-in-transit staff received minor injuries and received medical treatment at scene.
The man who was arrested was being questioned at Kevin St Garda station under Section 30 of the Offences Against the State Act.
Gardai in Kevin St are appealing for witnesses, in particular at the scene of the robbery on Cork Street, or anyone who may have seen suspicious activity prior to the robbery or who may have seen people fleeing from the van on Dolphin's Barn Green, to contact them in Kevin Street on 01 6669400, the Garda Confidential Line on 1800 666 111 or any Garda station.
