He was on his feet, just standing in the middle of the road. He collapsed with a wound in his back.
"We applied some pressure onto his wound as there was a lot of blood. We just wanted to make sure the lad was okay. I have never seen something like that, it was unreal.
"He was losing consciousness. A doctor from the surgery came and he was checking his heart rate and telling us what to do."
Zoheb Khan, 23, said: "We kept talking to him as we didn't want him to shut his eyes."
