Line Of Duty season 6 fans voiced their frustration and swore at the screen as the show dropped a huge, agonising cliffhanger at the end of episode four.

Last night’s episode of the smash-hit BBC crime drama (Sunday April 11) was a thrill ride with a tense shoot-out, deaths and plenty of returning characters.

However, just when viewers couldn’t take any more, the show revealed a cliffhanger that frustrated as much as delighted.

And now fans have to wait until next Sunday to find out what’s going to happen.

Fans speculated that Anne-Marie McGillis – John Corbett’s mother – could also be Jo’s mother, because of the photograph seen in episode one.

One fan wrote on Twitter: “Anyone else getting Anne-Marie McGillis vibes from Jo Davidsons Mum?

“Are Jo and John Corbett blood related #LineOfDuty.”
