There are already narrative concepts in the works for season seven, according to Line of Duty actor Adrian Dunbar, who plays Superintendent Ted Hastings on the hit police thriller.
The final head of the organised crime organisation AC-12 was the subject of many drama and accusations in series six.
On the other hand, the anti-corruption unit had to deal with the fact that adored character and important element of the unit DI Kate Fleming had been transferred to the murder investigation team, leaving former team members DI Steve Arnott and Superintendent Ted Hastings behind.
Even before it was revealed Ian Buckell’s had been codenamed “H”, many fans thought it was unlikely he could keep AC-12 on their toes for so long, let alone lead the world’s largest underground organised crime syndicate.
Fans began to wonder if the end of the season meant the lot of Line of Duty forever or if it would return for more drama and reveal the identity of ‘H’ shortly.
“I’m sure the BBC would like to undertake another season. For the simple reason that we’d like to get together again, “Dunbar spoke to GQ Magazine about his experiences.
“All of us exchange ideas, but I don’t want to share them with you. However, some elements of the storyline may come together to create a compelling seventh season.”
Since H was revealed to be Detective Superintendent Ian Buckell’s in the series six finales, it’s no surprise that fans desire another season to see if he’s, in fact, the bent copper they’ve been looking for.
There has been a lot of speculation about whether or not the programme has genuinely finished, but Jed Mercurio’s reaction earlier this year was unclear.
“To me, it’s a bit early. Those conclusions are premature at this point. Any of these options are possible as well as something completely different,” he teasingly said.
Chief Content Officer Charlotte Moore said: “I’m excited about having a dialogue with the team about where we will be going next and what the future of the series might be.”
BBC iPlayer has the first six episodes of Line of Duty, and DVD and Blu-ray boxsets are available now.
