Line of Duty's sixth series has had fans on the edge of their seats every week with viewers coming up with lots of theories about the characters in the show.

From H's identity to who Jo Davidson's relative is the series has had fans brimming with theories and twists.

And now some viewers have decided that AC-12's Chloe Bishop isn't quite who she says she is.

Many fans think that Chloe could be the daughter of Tony Gates from series one and is mixed up with the OCG.

The show already features Ryan Pilkington as a bent copper who was initially introduced in series one, as a child working for the criminal underworld.

And now lots of people have shared their theory on social media pointing to several things Chloe has done already in the series.

James Hodder said: "I am 110% convinced Chloe has a huge role to play in the latter episodes of this season. I think she is DCI Tony Gates’ daughter, holds AC-12 accountable for the death of her father and will do anything to bring them down. Am I right."

Helen said: "Calling it now. Chloe is getting revenge on AC12 for her dad who is Tony Gates."

Lucy Wray said: "I definitely think Chloe from AC12 is Tony Gates’ daughter from series 1, could she be part of the OCG?"

Another said: "Cmon everyone it's obvious Chloe leaked about Lakewell being in the convoy. Sideye at Buckells during interview? Couldn't reach van door so hoisting Josie up instead? Being the daughter of s. 1's Tony Gates, wi a serious axe to grind re AC-12? CHECK, CHECK & CHECK."

And Hutchfan said: "I think Chloe is Tony Gates' eldest daughter and she is the leak...the way she looked at Buckells when he was charged...and Steve spotted that. She was also on the lookout for OCG vehicle when in police escort of Lakewell."
