In Hackney, 2007, 15-year-old Abraham saves a stranger from a brutal attack. That split-second decision and act of astonishing bravery changes his life forever.

Journalist Sam Holder has been following Abraham’s story for years. Together with Abraham’s friends and family, they retrace how this young boy finds himself in fear of his own life.

This series explores the protections in place for witnesses of violent crimes, the obligations for witnesses to give evidence in court, and what can be done if someone feels their life is at risk.
