The first trailer for season six of the BBC police drama Line of Duty has been released

If you're a fan of Line of Duty, then get excited ...

Because the hit BBC police drama is back!

After two years of waiting, we've just had our first look at the sixth season of the police corruption drama with an explosive new trailer.

As usual, it looks like AC-12 will be involved in plenty of thrills, spills, and all-important interrogation interviews as they are drafted into action for a specially-extended season, which debuts on BBC One on March 21.

Vicky McClure, Adrian Dunbar, and Martin Compston will return alongside Shalom Brune-Franklin, a new addition to the AC-12 team.

Trainspotting star Kelly Macdonald will also make her debut as guest lead Detective Chief Inspector Joanne Davidson, the senior investigating officer on an unsolved murder case whose suspicious conduct attracts the attention of the anti-corruption feds.

There is no word yet on when the show will hit New Zealand screens.
