The scenes in court were difficult to watch as the youngster was subjected to intense questioning by separate barristers.
They made crude remarks about Holly’s (played by Molly Windsor) abuse and even made a joke about the size of one rapist’s penis.
At the start of the final instalment, viewers were informed that the comments made during the interrogation were taken from court transcripts in the 2012 Rochdale grooming scandal.
Those at home were disgusted to learn how the victims were addressed by the prosecution and took to court to express their fury that the young girls were blamed for the abuse they suffered.
Taking to Twitter, one viewer commented: “Omg the questions and insinuations! She was raped. She was a child. End of. #threegirls.”
Another explained: “This is disgusting. How dare they treat her like this when she’s the victim here. #threegirls.”
“I can’t comprehend how the judges are allowed to say those kind of things. #threegirls,” a third tweeted.
Someone else continued: “Was hoping tonight’s #threegirls would be slightly less harrowing but to think that the girls were actually subjected to this questioning.”
A fifth added: “Did they just make a joke about her rapists d*** size? EVERY WORD of what’s said in the courtroom is accurate #threegirlsbbc #threegirls.”
“These questions and suggestions are disgusting. So angry I don’t understand how someone can be a defence lawyer #ThreeGirls,” another shared.
Three Girls is available to watch on BBC iPlayer now.
