FIVE OF THE BEST

The Prosecutors

BBC2, 9pm

Drugs are big business in prisons. On the inside they can fetch four times their street value, and serving time can become a business opportunity for kingpin convicts. To prosecute the offenders, police need evidence of who’s involved on the inside – and who’s flying the packages in. Filmed over a year, with behind-the-scenes access to the CPS and West Mercia police, this two-part film follows Senior Crown Prosecutor Eran Cutliffe as she works to build a complex case against a network of people, who use drones to exploit the captive market.
