When paramedic Paddy Ennis arrived at the Manchester arena where a bomb blast had killed 22 people and injured dozens more, he froze.
Ennis, the first emergency service worker on the scene, was met with “overwhelming devastation”.
Then he noticed the screaming. Visibly injured victims were lying on the floor, yelling at him for help.
But instead of going to their aid, it was Ennis’ job to ignore them – there were people who needed his help more.
“The quiet ones were my first priority,” he told The Mail on Sunday.
“There were people screaming in pain and people terrified.
“But you have to ignore them because if they’re screaming the airways are open and you know they can breathe, so you are reassured by the fact they are relatively okay for now, although they had horrendous injuries.”
The North West Ambulance Service paramedic had arrived minutes after his daughter told him about the blast on social media.

The 38-year-old told the newspaper of how he quickly assessed injured people – checking that they were breathing and their pulse was at an acceptable rate. But not everyone the paramedic attended to could be helped.
“Unfortunately for some, my assessment was they were beyond any help we could provide.”
“They were already dead.”
So far, 14 suspects have been arrested in relation to the attack.
