The UK does not keep good statistics on the ethnic origins of criminals. This could be because authorities are worried that the statistics would lead to indigenous Britains blaming their elites for bringing large numbers of ethnic minorities into the UK without the consultation or consent of the indigenous population.
Similar countries keep statistics on the ethnic origin of criminals and the results are clear that men of some nationalities especially from Pakistan, Afghanistan, and African countries commit crime at many times higher rates than local inhabitants. Also men from other immigrant groups especially Europe and south east Asia commit crime at lower rates rates than indigenous people.
This data is readily available for Denmark, Germany, Sweden etc. You can easily google this.

We also know men of African origin are greatly over-represented in knife crime in London and muslim men are over-represented in jail in the UK.
