“It was the night before Mother’s Day and she came into the bedroom and she’d cut herself all over her body. I couldn’t believe what I was looking at and she just broke down.

“She just said to me: ‘Mum, I’ve been raped.’ We sat down and she told me everything – when it started, when the messaging started online.

“She said, ‘He pecked my head so much that I just gave in in the end and I met him.’”

A month after the alleged rape, Semina reported the incident to the police but the boy disputed it and no DNA evidence was found – it was her word against his.

“She thought it was all her fault,” one of her close friends tells McDermott. Semina became the target of vicious online attacks, being beaten up and bullied until she started refusing to go to school.

In June, Semina tried to take her own life and was put into a coma. Four days later, she passed away in hospital.

McDermott says: “I think Semina’s story is a real, extreme example of this deeply ingrained rape culture, most of which is stemming from social media, is stemming from porn, is stemming from so many things.

“No 12-year-old should have to be in the position where they are being pressured for sex and nudes from a boy.”
