An heroic teenager has been praised for dialling 999 and staying with a man injured in a hitand-run the day after a memorial service to his father.

Harefield Academy pupil Colin Daley, 13, was walking through Uxbridge High Street when he saw Peter Elder struck by an Audi TT sports car.

The quick-thinking teen was the first to call emergency services and stayed with Mr Elder before giving a statement to police.

Colin said: "I was waiting for a bus. The man got knocked down and I ran across the road with the phone to my ear calling police, and then I stayed with him."

Proud mother Lisa Daley, 41, of St Mary's Road, Harefield, said: "It was the day after we had a memorial service for Colin's dad and I think he wanted to get out and take his mind off things.

"I was a bit worried when I got a call from the police, but they assured me he was OK and hadn't done anything wrong."

Colin's father, Raymond Daley, 60, died on August 16 following an 18-month battle with lung cancer, just weeks before Mr Elder was injured.

"It's been a very difficult time for him and his 17-year-old sister, Emma," said Mrs Daley.

"We're so proud of him for stopping to help."

Earlier this month Sarah Sharpe, 24, of Hercies Road, Uxbridge, pleaded guilty at Uxbridge Magistrates' Court to failing to stop after an accident and was found guilty of driving without due care and attention.

A remorseful Sharpe told the court how she believed Mr Elder, of Kent Close, Uxbridge, was clipped by the car's wing mirror and not seriously injured.

But in fact Mr Elder endured a month in hospital with a broken wrist, leg and knee, resulting in him needing a wheelchair.

He also faces undergoing at least one knee replacement operation.

Mr Elder said: "It's had a massive impact. If it wasn't for my wife I wouldn't have been able to go anywhere."

Sharpe was fined £875, ordered to pay a £15 victim surcharge, £400 court costs and had 10 points added to her driving licence.

During the trial police praised Colin for his quick thinking.

Mrs Daley, who has nominated her son for a Gazette Local Hero award, added: "He was a little bit shaken up but I think he was pleased with himself. His dad would have been so proud of him stopping to help someone else."
