Black history month: 'I was first stopped when I was 16'
When he was 16 Aaron Rees was first stopped by the police while in London.
"Now I am used to it," he said. "That's just life. There's no point me getting angry over the situation [when white friends aren't stopped] - you've just got to ignore it and be the better man."
Now 20, Mr Rees is taking part in a project run by Cardiff City FC Foundation, where free football sessions are provided in a bid to steer young people away from criminal and anti-social behaviour.
Ali Abdi, from Race Council Cymru, said that young people were being treated unfairly and things needed to change.
