On 7 July 2005, Paul Dadge boarded an underground train heading towards the offices of AOL in Hammersmith, London. Like many that day, he did not complete his journey.
Forced to abandon his route, he continued on foot towards Edgware Road where the horror of 7/7 began to unfold in front of him. As survivors emerged from the station, Paul Dadge set up a makeshift triage area to care for the injured.
That morning he was photographed crossing the street and escorting one victim whose face was covered with a surgical mask. That image went right round the world within hours.
And for Paul, an incredible set of consequences followed that included almost standing for parliament and being a key figure in the Hacked Off campaign against press intrusion and phone hacking.
This is his story.
