A Neighbourhood Watch group compiles an impressive dossier of digital evidence that helps police identify two wanted burglars. Criminologist Dr Emmeline Taylor says groups like this can be a vital tool in the fight against crime.

Also, we see how a family of four had an incredible escape when the seafront hotel they were staying in went up in flames. Investigators uncover crucial evidence that proves the fire was started deliberately.
