Line of Duty Cast Spotted Filming Near Belfast City Airport Sparking New Series Hopes
Speculation that hit BBC police drama 'Line of Duty' could be returning to our screens has been confirmed, with the BBC officially announcing a seventh series after cast members Adrian Dunbar, Vicky McClure, and Martin Compston were spotted filming near Belfast City Airport. Eagle-eyed fans shared photos on social media showing the iconic AC-12 trio in character and surrounded by a film crew, sparking widespread excitement that a new chapter for the beloved drama is now firmly in production.
Background
'Line of Duty', created by Jed Mercurio, became a television phenomenon during its six-series run from 2012 to 2021. The show began on BBC Two before moving to BBC One for its fourth series in 2017, where it attracted a massive surge in viewers. It follows the investigations of anti-corruption unit AC-12, whose gripping storylines, labyrinthine plots, and nail-biting interview scenes captivated millions. The Series 6 finale drew in over 12.8 million overnight viewers — a 56.2% share of the UK television audience — making it the most-watched drama episode since modern records began in 2002.
While the first series was filmed in Birmingham, all subsequent series have been based in Belfast, with the city providing the gritty, unnamed backdrop for the fictional police force. Locations such as the Albert Clock, Bedford Street, and the East Belfast waterfront have become pilgrimage sites for devoted fans. The show's production has been a significant economic driver for the Northern Ireland screen industry, providing hundreds of jobs for local crew, actors, and supporting services over the course of a decade.
The Series 6 finale, which controversially revealed the identity of the arch-villain 'H', divided audiences. Many fans who had followed the overarching mystery for nearly a decade expressed disappointment, with some describing the conclusion as an anticlimax. Creator Jed Mercurio acknowledged the divided response, stating: "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."
Key Developments
The BBC has now officially confirmed that 'Line of Duty' will return for a seventh series, with filming underway in Belfast from spring 2026. The new six-part series will see the return of the principal cast: Adrian Dunbar as Superintendent Ted Hastings, Vicky McClure as DI Kate Fleming, and Martin Compston as DI Steve Arnott. The storyline will see AC-12 disbanded and rebranded as the "Inspectorate of Police Standards," with the team assigned to investigate a charismatic detective, DI Dominic Gough, accused of abusing his position as a sexual predator — though the case may prove to be a deliberate distraction from a far more significant threat lurking within the force.
The new speculation was ignited when photos and videos began circulating online showing the cast near George Best Belfast City Airport and the East Belfast Yacht Club, both familiar filming locations for the production. Martin Compston added fuel to the fire with a cryptic social media post simply reading: "Great to be back with my mates..." The BBC has confirmed the production is in full swing, with a broadcast date expected to be announced in due course. Source: BBC News.
Why It Matters
A return for 'Line of Duty' is a major television event. The show is one of the BBC's crown jewels — a critical and commercial success that has become part of the national conversation. Its return guarantees huge ratings and will dominate social media in a way few dramas can. For the BBC, it is a surefire hit in an increasingly competitive broadcasting landscape where streaming giants are constantly chipping away at traditional audiences. The show's popularity transcends entertainment; catchphrases like "Mother of God!" and "Now we're sucking diesel!" have entered the popular lexicon, and the AC-12 interview room has become one of the most iconic settings in British television history. Series 7 offers creator Jed Mercurio the opportunity to address some of the criticisms of the Series 6 finale and potentially give the beloved characters a definitive, satisfying send-off — or set up yet another jaw-dropping twist.
Local Impact
For Belfast and the wider Northern Ireland screen industry, the return of 'Line of Duty' is enormously welcome news. The production injects millions into the local economy and provides hundreds of jobs for local crew, actors, and supporting businesses. The show's success has been instrumental in putting Belfast on the map as a world-class filming location, attracting other major productions to the city in its wake. Belfast itself has become a character in the drama, and fans continue to visit famous filming locations across the city. The buzz and excitement around the city at the prospect of AC-12 returning to its streets is palpable, with local hospitality businesses already anticipating an upturn in fan tourism as the broadcast date approaches.

What's Next
Filming is now underway across Belfast, with the production expected to continue through the summer months. The BBC has yet to confirm a broadcast date for Series 7, but industry insiders suggest it could air as early as late 2026 or early 2027. All eyes are on Jed Mercurio and the AC-12 team to see which bent coppers they'll be after this time — and whether the new Inspectorate of Police Standards can uncover the truth behind DI Dominic Gough. Whatever the outcome, the return of Hastings, Fleming, and Arnott to the streets of Belfast has given millions of fans every reason to be excited.
