In Dublin, Ireland, one woman stood on the edge of a highway bridge and to thousands of commuters passing by, appeared to be threatening to jump.
As the woman held onto the outer edge of the railings of a bridge over a very busy commuter highway those who saw her were shocked at the possibility that she may jump.
Stopped truck underneath the woman
But one driver decided to stop and do what he could to help the woman, who was clearly in distress.
Photographer Keith Dunn captured the powerful moment when the driver stopped his truck underneath the woman to stop her from jumping into the path of oncoming vehicles.
