Line of Duty, the biggest new drama to air on UK broadcaster BBC Two in a decade, is preparing to return as filming gets underway on season two.
Shooting will begin in Belfast later this month on six new one-hour episodes, written by Jed Mercurio and produced by World Productions.
The cast, which includes returning Martin Compston, Adrian Dunbar and Vicky McClure, will be joined by Keeley Hawes, Robert Lindsay and Jessica Raine.
In a similar vein to season one, which averaged 4.2 million viewers, Line of Duty will return with a new story about police corruption that begins with the ambush of a police convoy in which three officers are killed and a protected witness is seriously injured.
The producer is Peter Norris and the executive producers are Mercurio, Simon Heath and Stephen Wright.
Season two of Line of Duty will air later this year.
