Harry Pitman, a 16-year-old schoolboy, was fatally stabbed in the neck on New Year's Eve while watching fireworks on Primrose Hill in London. The accused, also a teenager who was 16 at the time but is now 17, denies charges of murder and possessing an offensive weapon. Witnesses described Harry as having been in a fight before he was stabbed by the defendant, who allegedly used a hunting knife. Prosecutors argue the stabbing was deliberate, while the defense suggests it may have been accidental or in self-defense. Harry's death has been described as a tragic loss by his family and school, who remembered him as a bright and promising young man. The trial at the Old Bailey is ongoing and expected to last six weeks.
