The British-Indian population also includes tens of thousands of immigrants from Africa whose ancestors came from South Asia. Many of them are Muslims whose roots were from Pakistan or would have migrated to Pakistan after independence. This includes Gujarati Muslims, Ismaili Muslims, etc. They are counted with British-Indians but they feel closer to British-Pakistanis.
That would not matter when they are grouped as British-Indians will it..meaning if they do crime then they are classified as a British-Indian criminal.
No community has a propensity towards crime...if people have education and a 8-5 job,there is no time for crime.
