LINE of Duty has sparked confusion after cast members from EastEnders talked about the soap in bizarre scenes.
The BBC police drama has been a huge hit since it launched in 2012, and has had a number of former EastEnders actors guest star over the years.
However, one of the main characters was called Matthew ‘Dot’ Cottan, a clear reference to EastEnders’ legendary character Dot Cotton, played by June Brown.
But, if the EastEnders exists in the Line of Duty world, how did the detectives not spot that a number of former residents of Albert Square were in their company? And why would no one say anything?
For example Will Mellor played PC Rod Kennedy in Line of Duty, but was also bad guy Warren Stamp in EastEnders.
Meanwhile actor Tony Pitts played Chief Superintendent Hargreaves in the show, as well as Cliff in EastEnders.
Another actor to appear in both shows – which the detectives failed to pick up on – is Ace Bhatti, who played PCC Rohan Sindhwani and Dr Yusef Khan respectively.
Other examples to add to the soap conspiracy includes Jason Watkins who played Tim Itfield, as well as Albert Square’s Gerry Fairweather back in the late 80s.
And dodgy lawyer Jimmy Lakewell was played by Patrick Baladi, who played Dom in the BBC soap in 2003.
Last month, the BBC confirmed Line of Duty would be back this year.
BBC One dropped the trailer on January 3, revealing that a lot of fan favourites will be coming back this year, including Line of Duty and Killing Eve.
Returning for its sixth season, Line of Duty follows police officers Steve Arnott and Kate Fleming (Vicky McClure) as they investigate possible corruption in the Central Police force.
Line of Duty is already being teased by the cast and crew, with Martin Compston – who plays Detective Steve Arnott – shared the first page of his script on Instagram.
