Stalker Justin Rutherford confronts Daisy Midgeley on her wedding day in a Coronation Street scene that will end with a shocking acid attack.
The ITV soap worked on the storyline with The Katie Piper Foundation and Acid Survivors Trust International to highlight the devastating impact of such attacks.
In scenes to be shown next Monday, Justin, played by Andrew Still, turns up in the Rovers just as Daisy (Charlotte Jordan) prepares to leave for the wedding with Ryan Connor (Ryan Prescott) as chauffeur.
Justin advances on Daisy, sure he is going to ruin her day. Charlotte, 27, said the storyline took her by surprise.
She said: “I really didn’t see this coming. It’s not something you see a lot on TV, so I was really surprised.
“It’s just so evil just to decide to take away someone’s identity and someone’s face like that. It’s just so heinous.”
Producer Iain MacLeod said: “We were keen to show the long-term reality for people subjected to this kind of attack.
"The story will, at times, be heartbreaking but we felt it was an important one to tell.”
Sarah Green, chief executive of The Katie Piper Foundation, set up by model Katie Piper after she was the victim of an acid attack in 2008, said: “We were happy to support the team at Coronation Street to understand both the initial and long-lasting impact of an attack.
“Coronation Street have shown determination in their research to portray the reality of such attacks.”
In 2021, there were at least 420 reported attacks in the UK.
Jaf Shah, executive director of Acid Survivors Trust International, said: “Coronation Street is to be commended for confronting this particularly brutal form of violence.”
