The British cops had a cold-hearted message for the teen telling them a Muslim grooming gang had gang-raped her.

They told the 13-year-old she was a “prostitute.”

Over the last decade, there have been scores of gang rape trials showing cops, social workers and politicians in an ugly light.

As one former “sex slave” told a Manchester court, according to the BBC: “Everybody knew what was going on.”

Members of an alleged eight-man rape gang in Rochdale are now on trial for multiple sexual offences involving two underage girls. Among the charges are rape, indecent assault and indecency with a child between 2001 and 2006.

The first witness — known as Girl A — was 13 years old when she was allegedly victimized. The second alleged victim — Girl B — testified that cops and social workers knew she was being violated but “weren’t concerned enough to do anything about it.”

Girl B testified that, like many of the other rape gang victims, she was poor, vulnerable and living in a children’s home. Sometimes she would spend time in the Rochdale market where she met stall owner Mohammed Zahid, then in his 40s.

Every week, she said, she was taken to the dingy basement of a local shop owned by Mushtaq Ahmed. On a filthy mattress, she would allegedly be forced to have sex with Zahid, Ahmed and another man named Kasir Bashir.

When she wanted to escape their clutches, the teen turned to social workers and cops. Their response was jarring.

“They said I was a prostitute. I was prostituting myself,” she told the court. “I don’t remember them being concerned enough to do anything about it. I remember knowing that they knew what was going on.”

She added: “It always happened, it was nothing new to me. I assumed they all knew. The police had picked me up. It all just seemed to me everybody knew what was going on.”

The main factor why charges were not pursued was that authorities did not want to be called racist, prosecutors say. The girls who came forward were urged to do their bit for “social cohesion” and keep quiet

Prosecutor Rossano Scamardella told jurors both girls were sexually abused because their troubled backgrounds made them susceptible.

“They were children passed around for sex, abused, degraded and then discarded,” Scamardella said. “They became sex slaves.”

Girl B testified that she only escaped the gang’s clutches when she was fostered to a woman who was “like a mom.” The woman lived far away from Rochdale.

Years later, she said she tracked Bashir down via Facebook. She took a screenshot of his photo and contacted detectives. In addition, she spotted Ahmed selling produce out of a van near a local school and snapped a photo of his licence plate.

Girl B added that she waited for so long to act because “nobody did anything about it” when she was a child.

“I felt like that was my purpose. I think it had happened that much,” she said. “I never saw it as anything unnatural. I just felt like that was what I was there for. I normalized it so much in my own head.”

She added: “From the way I see things as a child to now, are two different things.”

Mohammed Zahid, Kashir Bashir, Mushtaq Ahmed, Roheez Khan, Mohammed Shahzad, Nisar Hussain, Naheem Akram and Arfhan Khan deny all the allegations against them.

The trial continues.
