THE fifth series of Line of Duty – produced by a Warrington resident – concludes this Sunday.

BBC's drama about the investigations of AC-12, a controversial police anti-corruption unit, has so far managed to pull in 8.3 million viewers at its peak, making it one of the most watched TV shows of 2019.

Winwick resident Ken Horn joined the team for this series of Line of Duty as producer after previously working on the likes of the BAFTA and Emmy-winning The Street and Our Girl, starring Lacey Turner.

Audiences are on tenterhooks to discover the identity of the infamous 'H' in what writer Jed Mercurio said could be the last episode.

Line of Duty is on BBC 1 at 9pm on Sunday
