Dublin Fire Brigade rescued a man from the River Liffey earlier this afternoon.
The individual was helped out of the water using a rescue boat.
Firefighters from Dolphin's Barn, Tara St and Phibsborough stations attended.
One onlooker wrote on Twitter: "Just happened upon the distressing sight of some poor divil (alive, but clearly in a bad state) being fished out of the River Liffey at Heuston Station Bridge.
"More than a dozen ambulance crew and fire brigade men working to get him out of the water. Hope he gets looked after."
