A man is on the run from Operation Bosun, Bedfordshire Police's specialist unit who tackle gun crime. Police believe that the wanted man is lying low for the moment but remains armed and dangerous. Gun crime is a force priority: in just six months Bedfordshire Police have dealt with dozens of reports of weapons being discharged and have seized 23 firearms. Finally officers spot their suspect and call in armed back-up. The attempted arrest is a moment of high tension and drama that plays out in an ordinary street in an ordinary town. This isn't a crime thriller; this is real life. 24 Hours in Police Custody, the critically acclaimed documentary series that follows the work of Bedfordshire Police around the clock, has a fresh approach to capturing their investigations into major crimes. Cameras follow each case in forensic detail as officers race against time to disentangle the evidence and build a case, which they then dramatically put to their suspects in interview.
