Line of Duty will return to BBC One in early 2021
Filming for the new series started up again in September and is still ongoing, with Adrian Dunbar, Vicky McClure and Martin Compston reprising their roles as detectives Superintendent Ted Hastings, DI Kate Fleming and DS Steve Arnott.
AC-12, the anti-corruption unit, will be met with a new, inscrutable adversary called DCI Joanne Davidson, played by Kelly Macdonald (Giri/Haji),
The series will pick up a year and a half after the closure of Operation Pear Tree, with Hastings returning to head up the unit after his exoneration at the end of series five.
