The brother of murdered teenager Jimmy Mizen has posted an emotional tribute as he steps down from the family's charity.

Jimmy was just 16 when he was killed in an unprovoked attack in a bakery in Lee Green in 2008.

After his death, the Mizen family set up For Jimmy, a charity that aims to confront youth violence at its roots by trying to stop children falling into crime.

The charity has been running for 10 years and has been praised for its work.

At a memorial service for Jimmy on the 10th anniversary of his death, Margaret Mizen called for a "community effort" to tackle knife and gun crime in the capital.

She added it was important for her to forgive her son's killer, saying: "Wouldn't it be better if there was much more forgiveness in this world?"

Now, just months after this anniversary, Jimmy's brother Billy has announced he will step down from his role as CEO of For Jimmy.

In a moving statement posted to Facebook, Billy said: "When our family lost our beloved Jimmy on 10th May 2008, it changed our lives irrevocably."

He added he was pleased with the charity's work to combat the causes of youth violence.

Billy said: "I am proud that we have shown to young people that they matter, that they have worth, that they have positive, meaningful roles to play in our society.

"I am proud that we have not ignored young people’s pain in the hope that it goes away.

"I am proud to say we have helped, and will always help, young people believe in themselves."

Billy's statement also acknowledged the harder times the charity has faced, saying at times it felt "overwhelming" to face up to the problems facing society as a whole, but he added: "we have never given up."

Paying tribute to his colleagues, Billy also praised his parents for their outlook.

"Still, to this day, I am inspired by the words and actions of my parents Barry and Margaret and will take that inspiration with me as I enter into a new era of my life," he said.

As Billy announced a new CEO will be taking over - who has not yet been named - he paid a final tribute to his brother.

"Finally, I would like to thank Jimmy. It has been an honour and a privilege to lead his charity. It’s a charity like no other. It has and always will be for him."
