According to this:
www.bbc.co.uk/news/uk-england-oxfordshire-22164676
The leaders of the gang are:
'thought to originate from Eritrea, in East Africa, but he grew up in his parents' house on the Cowley Road.'
Since when was Eritrea in Asia?
The Telegraph goes with:
www.telegraph.co.uk/news/uknews/crime/10057543/Asian-grooming-gang-convicted-of-appalling-acts-of-depravity-on-children.html
"Asian grooming gang convicted of appalling acts of depravity on children"
yet in the article concedes:
"Seven men of Asian or North African origin were found guilty of grooming"
It seems like inaccurate and prejudicial language to me, especially when Asia contains 2/3 of the population of the world yet 'Asians' are obviously an ethnic minority in the UK.
