Mr Casal gave evidence at the Old Bailey after Damilola's mother rushed from court today, unable to watch film of her son skipping innocently to his death. Gloria Taylor was comforted as CCTV footage showed the boy playing outside a library after school. His silver jacket - which it is claimed made him a target for a gang of teenage robbers - is clearly visible. Finally he disappears out of sight of the cameras. Moments later, the prosecution alleges, he was surrounded by four members of a south London gang and stabbed in the leg with a broken bottle. A marble was put in his mouth to stifle his cries, the court was told.
