Andy made a failed bid to escape his captor
Coronation Street fans were horrified tonight after 'psycho' Pat Phelan turned up his aggression on poor Andy Carver.
Viewers discovered that he was being kept alive by the resident villain on the cobbles - hidden deep inside a derelict house.
And Andy made a failed escape bid, which really got on Pat's nerves, so he furiously swung around a hammer and threatened to silence him once and for all.
Pat was nearly caught out after his daughter Nicola followed him to the address and started asking questions.
Eileen had noticed his bizarre behaviour and confided in Nicola, who was worried by a gash on his head.
With the two ladies in his life fussing over him, Phelan lashed out in anger at a terrified Nicola and was left on edge.
He headed back to see Andy and was kind enough to leave him a sandwich.
Trying to scare Andy, he said: "You don't need to worry about sleep, you've got a big sleep coming to you."
He managed to restrain himself, but viewers were traumatised when Andy was left in the dark with a filthy rat.
The dishevelled prisoner repeated: "My name is Andy Carver and Pat Phelan has me hostage."
Corrie viewers took to Twitter after witnessing the shocking scenes.
One viewer said: "Oh my god an actual rat in there with him though. #Corrie "
A third said: "What's Andy moaning about, his pet rat is really cute #corrie "
