Line Of Duty actor Lennie James has revealed that the show's creator Jed Mercurio has written a scene bringing his character back from the dead.
James played detective Tony Gates in series one of the corrupt cop drama.
Speaking to Digital Spy on the red carpet of the TV BAFTAs, Lennie revealed: "God's honest truth, he came in one day and said: 'I've just written a scene where Tony Gates comes back,' and I was like: 'Yes, finally,'" he revealed.
"Then he came in the next day and said: 'I read it again and it was rubbish.'"
He added: "That's what he does with people. So he might do it again, he might not, I don't know. You'll have to ask Jed...."
He might do it again, he might not, I don't know. You'll have to ask Jed...
Gates is thought to have been killed off "in the line of duty" after being hit by traffic in series one, but now fans of the show are speculating that the character might not be dead after all.
One theory is that Lisa McQueen, a member of the series five OCG, is actually his secret daughter with Jackie Laverty – the money launderer who was murdered in series one.
Other fans have speculated that Gates is still alive and the leader of the OCG.
Whether Lennie returns for series six of the BBC drama is yet to be revealed, but he is set to resurrect his role of Nelly in Sky Atlantic's brilliant Save Me.
