Paul Dadge, who is pictured helping a wounded woman in many newspapers, was back at King's Cross on Friday morning determined to send a message of defiance to those behind the attacks.

Paul Dadge says he did not think twice before helping the victims

The former firefighter had been on a Tube travelling to work in Hammersmith on Thursday when his train was terminated at Edgware Road, so he started to make his way there on foot.

At Marks & Spencer's on Edgware Road about 20 of the seriously injured and some 100 walking wounded were being brought into a makeshift triage unit at the back of the store.

With just basic first aid skills, the 28-year-old jumped in to dress burns and take victims' details.

Another security alert forced them to move across the road to the Hilton Metropole Hotel.

It was at that point that the picture which appears in many of Friday's papers was taken.

He knows only that the wounded woman may have been called Davinia. "She had suffered some superficial burns to her face and lacerations to her head," Mr Dadge said.

He insists he did not think twice before jumping in and will be cross if he is labelled a hero.

"I saw an awful lot of walking wounded. I didn't have time to think about myself, It's just my natural instinct to get involved. I'll always be in the wrong place at the wrong time."

He helped five or six people with burns injuries before carrying on to work, where he admits not much got done once the full scale of the tragedy became clear.

Mr Dadge said: "I can really give a useful message to whoever's responsible and say you won't affect us here in London.

"Most offices have told people to stay at home [on Friday] but once those Tube lines have been cleared we will be back in our offices."

George Psaradakis, 49, was the driver of the Number 30 bus ripped apart in the fourth of Thursday's blasts.

George Psaradakis said his bus had been diverted after the Tube blasts

My bus had been diverted because there were thousands of people coming out of the Tube.

There were many people who were trying to get on the bus at once.

Suddenly there was a bang, then carnage. Everything seemed to happen behind me.

I am just relieved to be here and to be able to see my wife and children.

Many other people have not been so fortunate. I feel for the people who have perished and for their families.

Martin Bailey, 54, had dropped his daughter off at work near Holborn station and was returning home when he pulled up alongside the Number 30 bus at 0947.

Martin Bailey's car was showered with debris from the bus

His abandoned car is a wreck. Photos of the scene show the windows shattered and a large chunk of debris across the roof, but he escaped unharmed.

I was heading north and the bus was heading south. I saw the driver talking to two parking attendants on the other side of the bus, and then all of a sudden there was an explosion.

I dived for cover and laid across the front seats until the debris had stopped falling.

Then I managed to get out of the car through the passenger's side and walked down a side street.

I didn't stop to look around, but there were bodies lying everywhere. I was shaking a bit, and I tried to make a call but couldn't get through.

I remember seeing a body laying between my car and the bus. The side streets had lumps of body in it.

[The experience] is very vivid. It was a very loud bang - my eardrums were nearly blown out.

After the bang there was all the noise of the debris falling down.

I didn't even know the glass on the car had been shattered.

I slept OK last night and I'm fine now.

The car is still there, I think. Forensics are looking at it and I've given a statement to police.

Ade Oshungboye, 26, was travelling on a bus ahead of the one that was blown up in Tavistock Square. He took photos of the ensuing scenes as he headed towards the wreckage.

After I'd been on the bus for about six minutes, I heard a big bang, and thought it was just a noise.

But then people on my bus started screaming and yelling, saying 'oh, my God, oh, my God'. Our bus stopped and people just started running away, but I moved towards the [bombed] bus.

I saw a lady with blood on her and her clothes ripped. There was a lot of blood at the back of her head, but I don't know if it was her blood or someone else's.

Other people were just trying to help her, getting her to sit down, but she kept screaming.

I got within two metres of the bus but the police were trying to get people away. I saw some people helping a man but I don't know if he was alive - his head seemed to be hanging out of the window.

There was a body lying on the ground, but I don't know if it was actually moving.

I had been with my brother just before and I knew he was supposed to be near the street but we met up after about 15 minutes.

Right now I'm OK, but [on Thursday] I couldn't believe it. I had to call my family and friends and tell them what I had seen.

Mark Margolis returned to King's Cross on Friday morning, 24 hours after he was injured in one of four blasts that rocked the capital's transport system.

With a bandage above his left eye and scratches on his face, he recounted his journey from Finsbury Park, north London, to work at a software company in Fulham, west London.

We stopped at King's Cross, people got on, and then we moved off.

I just heard a bang and then all the lights went out. Glass flew everywhere, people were screaming.

At that point we thought it was derailed or something like that.

I feared fire. If there was a fire I didn't know how we would have got out of there.

The driver managed to open the doors but because people were screaming we couldn't hear him.

I tried to keep calm, I felt my body to find out if I had any injuries. I found blood on my face.

All the windows were blown out. I remember getting out. I held onto the guy in front of me.

Everyone pulled together, everyone was helpful.

I left [my wife] a message at work. I started off by saying I am absolutely fine, which of course made her more worried because you never start a conversation with 'I am absolutely fine'.

I explained I had some cuts and that I was shaken.

I'm here because my first reaction [on Thursday] was I don't ever want to go on a Tube again. The longer I leave it, the worst that will become and I don't want this to affect me.

I hope we look at the wider effects, I hope we don't blame a particular religion. If we fall into the trap of blaming people, it's just wrong.

Scott Wenbourne told the BBC on Thursday of his experiences on the tube between Aldgate and Liverpool Street.

Uninjured, he is at home recovering from the shock.

Luckily I don't have a scratch on me, but it's really starting to sink in hour by hour.

Although I was lucky, I can't stop thinking about those poor people who had their lives snatched from them.

I wasn't able to sleep last night - every time I shut my eyes I get images of those people I saw on the tracks.

I can't shut out something of this magnitude. The images won't ever leave me, it was just horrendous, but I hope they will lessen.

I've been watching the news and seeing people say that they will get back on the tube and get on with life, but I will not be getting on a tube. They didn't see the damage from the bomb and I did.

I will eventually get on, but not for a very long time.
