Coronation Street star Chris Gascoyne has revealed that there are tough times ahead for his character Peter following the death of Stephen Reid (Todd Boyce).

Murderer Stephen's reign of terror came to an end on Friday when he was run over in the street by Peter, moments after he had threatened to kill Jenny (Sally Ann Matthews) with a broken bottle.

In tonight's episode, Peter is arrested on the suspicion that he may have deliberately murdered Stephen in a fit of revenge - and in the weeks ahead, Peter will start to question his own motives.

"This is where Stephen's story ends and mine picks up," said Gascoyne, who will be departing the soap in the near future. "Peter is a man who is in deep conflict with himself.

"At the end of the day it doesn't matter how it happened, he has killed someone. It is impossible to imagine what that must feel like. Could you ever rest, could you sleep?

"He actually says 'I have taken another human being out of this world forever, what kind of person does that? What does that make me?' And he is terrified."

Peter's worries take a turn for the worse when he learns that Stephen had let go of the bottle before he hit him with the car - and it could see recovering alcoholic Peter turning back to the booze.

"He is in hell and he is fighting through fear, but when he knows that Jenny is pretty adamant she would have been ok, that really starts to affect his mental state of mind," Gascoyne continued.

"As we know Peter has been through a lot and there is no doubt that he will be tempted to drink which really would be a decision to kill the pain and kill himself through alcohol, he knows that.

"This is a real danger zone for him. He has taken a man's life and even if he goes to prison he will have to live with that, he will always suffer. It will be interesting to see how he deals with his demons."

Coronation Street continues Mondays, Wednesdays and Fridays at 8pm on ITV1 and ITVX.
