Stuart Lawrence has told the Daily Mail:
I am being targeted because of the colour of my skin, I don't think it's because I am Stephen's brother.
Whenever I have been stopped, I have never subsequently been charged with anything, and nothing has ever been found to be wrong with my car.
I have never, ever, done anything wrong. I have never been in trouble with the law. I have paid my road tax and my insurance, and always tried to keep my cars in a roadworthy state.
