Big Little Crimes tells the remarkable stories of ordinary beat coppers who stumble upon a key piece of evidence — a haul of stolen goods or a suspect on the run — and bring a major criminal to justice. Two PCSOs are caught in a web of lies designed to discredit their colleague. A tip-off leads to police cracking a £2 million insurance scam, and a married couple rip off thousands of concertgoers with extortionate ticket prices.
