A new true-crime series on BBC Two revisits the 1994 murder of Shamsuddin Mahmood in Orkney, a case that shocked the remote island community. The 26-year-old was shot dead while serving food at an Indian restaurant. Fourteen years later, teenager Michael Ross was convicted, but he continues to deny the crime from prison.
Journalist Hazel Martin re-examines the evidence and speaks to Mahmood's family, Ross's mother, and others involved in the case. The series promises to reveal new insights into the investigation and the controversial conviction.
Also airing tonight, Channel 4's 'The Cancer Revolution' features Cambridge neurosurgeon Richard Mair, who is pioneering faster tumour DNA analysis to deliver effective drugs sooner. Meanwhile, Sky Atlantic's 'The Death of Bunny Munro' continues, and BBC Three's 'The Summit' returns for a ninth series.
