A special edition of Crimewatch marking 30 years of crime solving.

Since its first broadcast in 1984, Crimewatch has appealed for help with thousands of cases, including most of the major crimes of the past three decades; from the bombing of the Grand Hotel in Brighton in 1984, the kidnap of Stephanie Slater in 1992, the murder of James Bulger in 1993, the murders of Lin and Megan Russell in 1996, the shooting of 11-year-old Rhys Jones in 2007, the disappearance of Madeleine McCann in 2007, the disappearance of Claudia Lawrence in 2009 and the murder of Joanna Yeates in 2010.

To date, Crimewatch has featured over 4,500 appeals including 758 murders, 339 rapes and 926 robberies. Every UK police force has appeared on the programme. The types of crime featured have been incredibly diverse, ranging from money laundering, kidnapping, hijacking, paedophilia, people trafficking, drug dealing, rioting, terrorism and drug dealing.

Crimewatch's impressive track record shows that around 1 in 3 cases featured lead to an arrest with 1 in 5 leading to a conviction. Given the appeals usually relate to harder-to-solve crimes this demonstrates the remarkable impact of Britain's armchair detectives.

Alongside new appeals, reconstructions, wanted faces and CCTV this special programme looks back at many of Crimewatch's biggest cases and hear from former presenters Nick Ross and Sue Cook about their years at the helm of Britain's biggest crime show.

The programme also returns to meet some of the relatives and survivors of Crimewatch appeals past to see how their lives have moved on. Amongst those featured are Kate and Gerry McCann, Shaun and Josie Russell and Sally Anne Bowman's father Paul. Show less
