Parents went to police and the authorities
"At the same time, she said, her family were being threatened and intimidated.
"The men were parking outside my house, they were threatening my family, they were ringing my house phone - and they were quite dangerous men as well.
"The police said they couldn't offer any protection, so because of that I decided to drop the charges," she added.
"I was 13 at that point and my sexual exploitation went on until I was 15," Emma said.
She said her mum was the first person she had told what was happening. But even her family were unable to stop the abuse.
"My parents went to the relevant services, they went to the people who should have been there to help and protect (me), because as a family we couldn't stop these people," she said.
Emma said her parents even locked her up - "as many other parents" of victims had done - but said threats from the men left her fearing for her family's safety.
"I had no choice really, because they used to threaten to get my mum and rape my mum. So in my mind, as a 13 or 14-year-old, it was 'well if I didn't go out and see them they are going to get my mum and are going to rape her'.
'They knew everything'
"They gang raped me, so what stops them from doing that to my mum?" Emma said.
She added: "They used to follow my mum because they used to know when she went shopping, what time she had been shopping, where she had gone.
"They made it quite clear to me that if they wanted to harm somebody I loved to get to me in any way they would do that, if that's what it took."
In the end she says her parents decided the only way to stop the abuse was to move her "out of the country".
In the meanwhile, Emma says her perpetrators were able to "walk the streets and were left unpunished".
