Here's an article from 2023 discussing the issue which we are being told was never addressed before'. That said, it's devoid of the gory details which have been highlighted most recently.
It comes as Home Secretary Suella Braverman made several comments about the ethnicity of abusers in high-profile gangs.
In the Mail on Sunday she said "the perpetrators are groups of men, almost all British-Pakistani".
To the BBC she said the gangs were "overwhelmingly" made up of British-Pakistani males.
The grooming gangs were not made up of immigrants, therefore you can't 'send them home'.
The article is critical of both the police and government of the time who did a terrible job of addressing the recommendations and worth reading.
A previous piece of research from 2015 found that of 1,231 perpetrators of "group and gang-based child sexual exploitation", 42% were white, 14% were defined as Asian or Asian British and 17% black.
The problem is that the data is from only 19 out of more than 40 police forces and nearly a decade old.
As far as I can find out we are still working from the 2015 numbers.
In 2022 the Independent Inquiry into Child Sexual Abuse investigated abuse in six cities which had not experienced a high profile grooming case.
It found evidence that gang-based abuse was happening, and of widespread failures by the police to record the ethnicity of perpetrators.
This "makes it impossible to know whether any particular ethnic group is over-represented as perpetrators of child sexual exploitation by networks," the report concluded.
Basically the data and reporting have been terrible but It's still not immigrants doing this awful stuff. These people were born here, which somehow makes it even worse.
