In 1992, two-year-old James Bulger was abducted from a shopping centre in Bootle, on the outskirts of Liverpool, by two ten-year old boys who tortured and murdered him. His body was found on a railway line in nearby Walton two days later.
Robert Thompson and Jon Venables were convicted of his murder in November 1993. Both were aged 11 at the time, making them the youngest convicted murderers in modern English history. They served eight years and were released in 2001 on a lifetime licence, with new names and new identities.
In 2010 however, it was revealed that Jon Venables was being returned to prison, charged with possession and distribution of indecent images of children.
