Line Of Duty fans point out ‘huge spoiler’ after Jed Mercurio shares snap from filming

Line Of Duty fans have claimed to have pointed out a ‘huge spoiler’ after show creator Jed Mercurio shared a snap from filming on Monday.

The writer, 54, took to Twitter to share a collection of photos of DS Steve Arnott, played by Martin Compston, Ted Hastings, played by Adrian Dunbar, and DI Kate Fleming, played by Vicky McClure, as they playfully posed on set. 

Yet eagle-eyed fans were quick to point out that DS Steve Arnott had lost his ‘sergeant stripes’ from his uniform as they questioned whether he had been demoted or was going undercover.

Line Of Duty resumed filming in September after a five-month hiatus during the COVID-19 pandemic. 

The BBC police drama suspended shooting for series six back in March, but leading actor Martin Compston – who plays DS Steve Arnott – returned to set to shoot socially-distanced scenes last month.  

Show creator Jed thanked fans for their ‘patience’ and assured that the cast and crew are aiming to have the sixth season back on air ‘as soon as possible’.

In one of the photos from the set, Martin posed as his character DS Steve Arnott while sitting behind a glass wall, which appeared to be in a prison. 

The cast surrounding him are all wearing face masks and remain at a social distance on the other side of the screen. 

Martin also posted the picture to his own Instagram where he captioned it with: ‘Officially back in business #waistcoatup #lineofduty6.’ 

The actor also posted a fun snap of himself getting his longer locks, which he grew during lockdown, cut by hair stylist Cat Coogan.

‘But following our implementation of all the industry Covid protocols, we’re delighted to be able to resume filming series six safely.’

The hit BBC One police drama suspended its filming in Belfast for season six in March to adhere to the COVID-19 regulations.

A BBC spokesperson said at the time: ‘In light of the spread of Covid-19, after much consideration, the producers Caryn Mandabach Productions and Tiger Aspect Productions of Peaky Blinders Series 6 have postponed filming, and World Productions on Line of Duty Series 6 have suspended filming, both in consultation with and supported by the BBC.

‘We will continue to review all productions on a case-by-case basis and will continue to follow the latest news and advice from the Foreign Office, World Health Organisation and Public Health England.’  

The sixth series is rumoured to air sometime in 2021 – although no date has been confirmed. Series five aired from March-May 2019.

The show, which stars Martin as DS Steve Arnott, Vicky as DI Kate Fleming and Adrian as Superintendent Ted Hastings – following anti-corruptions officers as they root out bent coppers in the AC-12 division.

In August, Martin explained the cast are hoping to have the forthcoming sixth season shot before Christmas.

Appearing on The One Show, he also teased storylines for the upcoming series as he insisted that ‘the scripts are so good!’

He said: ‘In terms of the changes… we really wouldn’t want to compromise the scripts, the scripts are so good, and people are so loyal to the show, there would be no point coming back if we’re going to compromise quality.’

The show’s writers are notoriously tight-lipped when it comes to storylines, and so when quizzed about whether there is, as rumoured, a ‘massive bombshell’ at the end of episode four, Martin teased: ‘Well there’s a few before that as well…

‘But just because I don’t have script five, there’s a big, big question at the end of [episode] four.’
