The Emmerdale cast member, who has played Eric Pollard on the ITV soap since 1986, made the comments on his private Twitter page.
In a screenshot obtained by The Mirror, Chris Chittell, 70, referred to an article about Emmerdale’s Maya Stepey and Jacob Gallagher grooming plot as “every young man’s dream”.
The article was titled ‘Emmerdale producer reveals child abuse storyline for Maya and Jacob’.
Witnessed by his 9,350 followers, Chris added: “Come on, it’s a young man’s dream. Okay okay I know, behave et bloody cetra [sic].
“Come on, it’s a young man’s dream”
“Don’t they ‘play’ it well!! Convincing don’t you think!!!”
Emmerdale fans blasted the actor over the comments, with one writing: “I doubt you’d be making comments like that if it was an adult ale grooming a teenage girl. #idiot.”
Another added: “Is Chris Chittell joking? How can he make such thoughtless remarks in this day and age?”
The storyline sees Maya (played by Louisa Clein, 39) get attached to pupil Jacob Gallagher, played by Joe-Warren Plant, 16, with the pair recently kissing.
Emmerdale bosses have been working with Barnardo’s on the storyline, with young survivors of sexual abuse giving advice to actors and producers.
Producer Laura Shaw said: “It was important for us to tell this storyline authentically, so we approached Barnardo’s for advice on scripts and character behaviour.
“Our researchers, story team and actors met with Barnardo’s experts and young men who have been supported by the charity.
“Hopefully it will make young people and their parents more aware of these issues and their impact.”
Barnado’s chief executive Javed Khan also said that “outdated” views still exist on boys who are groomed my adult women.
He commented: “We were really pleased to be approached by Emmerdale to advise on the serious subject of adult women grooming and abusing boys. Too often this is seen as ‘taboo’ and not talked about.
