This, from 2017, seems quite interesting:
https://www.channel4.com/news/factcheck/what-do-we-know-about-the-ethnicity-of-sexual-abuse-gangs
"According to the best available data, Asian men make up 75 per cent of “Type 1” group abusers, who target children and young women because they are vulnerable.
But white men make up 100 per cent of recorded “Type 2” group abusers, who target children because of a longstanding paedophilic interest.
From the information available, we know that actual number of group abusers who are Asian is around three times higher than the number of group abusers who are white."
While "Abuse by lone offenders is much more common than abuse by groups [...]CEOP’s report doesn’t include data on the ethnicity of lone child abusers, and the government doesn’t publish comparable information."
So of the statistics we have, we know that Asian men are 75% of opportunistic group sexual offenders against children and teenage girls, while paedophiles who commit group sexual offences against children are white.
So...white men only tend to commit group sexual offences against children if they're paedophiles, while Asian men will do it opportunistically, despite not having specific paedophiliac interests? That's what I'm getting from it. Although I'm not sure how they work out that the Asian men aren't paedophiles if they're sexually offending against children?
Additionally, as the government doesn't include data on lone offenders, we have no clue whether the offending profile for lone abusers is the same as for group abusers, or whether it varies.
