One of them, Steve Higgins, 30, said: "We ran down and saw he had badly hurt his leg and his side. I took a first aid course last week so that gave me the confidence to go and help him. He was getting really cold because there was so much blood running out of him so we covered him in our high-vis jackets until the ambulance arrived. I held his hand and kept asking him if he was ok and he replied 'yes' but he couldn't feel anything."
