The father of Damilola Taylor told The Independent on Sunday last night that he is convinced the two brothers cleared of murdering his son had killed him.
"All the evidence in the case is pointing an accusing finger at them. They did it," said Mr Taylor.

They should hide their faces in shame rather than being allowed to go about telling the world they didn't do it."
One of the brothers told the BBC yesterday: "I never did it and I wasn't there - so sorry. …
