Streatham ice rink murder witnesses 'still afraid'
The mother of a teenager shot dead in south London four years ago has said potential witnesses "are still afraid of speaking" about the crime.
Tracey Ford held a vigil on Thursday in memory of her 17-year-old son Andre Smartt-Ford, who was murdered at Streatham ice rink on 3 February 2007.
A £20,000 reward was offered by the Metropolitan Police to find the killer.
Mrs Ford told BBC London 94.9's Louise Pepper why she felt the crime remained unsolved.
