His father is Somali and works for the Somali government, so you can drop the accusatory speculation. It’s likely he’s British-born though and the usual word in the UK would be “heritage” not “origin”, which as you say implies that someone was born elsewhere. When talking about a hate crime the ethnicity of the perpetrator is hardly irrelevant. And for any terrorism-related incident the first question is going to be whether or not the perpetrators were domestic or foreign (especially if they just murdered a member of the government) - as this shapes the response massively. If this person was raised abroad and brought radicalism with them that’s totally different from someone raised in the UK who has been radicalised online (or possibly even in the community).
