For 17 years serial rapist and burglar Delroy Grant – who  became known as the ‘Night Stalker’ - terrorised elderly people in south London, cutting phone lines before breaking into homes and carrying out horrific sex attacks on victims as old as 93. Award-winning Daily Mail crime writer Stephen Wright speaks to ex Metropolitan Police DCI Colin Sutton, whose battle to capture Grant is now an ITV drama starring Martin Clunes, on the near-miss that left Grant free to attack more victims, and how his team finally tracked down the monster and saw him jailed for 27 years for a string of rapes, sex assaults and burglaries.
