Speaking in September 2018, series creator Mercurio said: “With Line of Duty we’re shooting series 5 now, and series 6 has been commissioned which we’re gonna shoot hopefully in the next couple of years.
“So yeah Line of Duty should be on air, series 5 early in 2019.”
He revealed: “There are things we haven’t done before, characters we haven’t seen before and that I think’s part of the construction of the series.”
Who will star in series five?
Adrian Dunbar, Vicky McClure and Martin Compston are confirmed to be reprising their roles as the officers of AC-12.
Line of Duty usually has a guest star as the focus of each investigation – previous series have seen Keeley Hawes and Thandie Newton among those to come under scrutiny – but season five’s casting is yet to be announced.
