His post read: "A friend of mine was cast in series 7 last week. There’s no secret." 

The BBC has yet to confirm or deny if a new series is in the works, but with the finale pulling in an average of 12.8million viewers, it is surely an attractive proposition.

Show star Martin Compston and writer Jed Mercurio have also remained tight-lipped over its future, but they have responded to fan disappointment over the climax.

Having masterfully crafted 10 years of suspense and drama surrounding police corruption, it was almost inevitable that the programme's big climax wasn't going to please each of its 13 million viewers.

And so it proved to be as blundering Ian Buckells was unveiled as crime boss H.

Many felt the hapless detective wasn't capable of giving AC-12 the run around for so long, let alone commanding respect in the criminal underworld.

Addressing the response, Martin wrote on Twitter: "Hey folks now the madness is slightly dying down just want to thank everybody who reached out about last night and the series as a whole, we've truly been blown away by the reaction and love for the show we're proud of it.

"Felt many emotions from excitement and anxiety at the hype to relief that it's over. Now I just feel immense pride our show that started on Wednesday's on BBC2 has just smashed every overnight drama record since they began. Fully understand it wasn't the 'urgent exit' type ending some anticipated but we appreciate you sticking with us [heart emoji]."

While writer Jed retweeted his pal's post and wrote: "We're honoured and flattered by the viewing figures for #LineofDuty6. We knew attempting to explore the real nature of corruption in our society wouldn't appeal to everyone, but we do sincerely thank you all for watching. It's been our privilege to share your Sunday nights."

Steve Arnott actor Martin also revealed he made a pact with his co-stars to get matching AC-12 tattoos ahead of the series finale's ratings success.

A whopping 12.8million people tuned in to see the series showpiece.

And now the show's biggest stars Vicky McClure, Adrian Dunbar, Martin and Jed could be getting a permanent tribute to mark the achievement.

Martin wrote: "Finally myself, Vicky, Adrian and Jed made an agreement in the inconceivable and ridiculous scenario we ever got twelve million viewers we would get 'AC12 million' tattoos. We'll see who's good to their word......"

AC-12 is the name of the anti-corruption unit the trio work for in the programme.

Ahead of the hour-long finale, Martin revealed he was racked with anxiety.

While the ending appeared to tie off the decade-long investigation into H's identity, there were hints that there could still be bent coppers running amok.

Buckells gave a knowing smirk as he was led into his cell leading many to believe the game isn't over.
