If that guy did exist, he'd probably have zero understanding of the law and the justice system and get himself rightly locked up. This is actually a perfect example of what Robinson doesn't understand. We had 2 related trials, which now everything has been concluded the media are reporting. If they're trying to hide anything, then the BBC, Guardian, Independent, Mail, Express, The Sun Talk Radio, Oxford Mail and the Crown Prosecution Service seem to be doing a terrible job of hiding it.
Sigmar, in common parlance in the UK ,"Asian" would typically refer to someone from the Indian subcontinent. If those involved are as you suggest from multiple countries it seems perfectly reasonable to use "Asian". If they are from Britain, but of Pakistani/Kashmir descent, again, using "Asian" makes perfect sense. Also, several places did use the name/age/address in their reports.
I do enjoy the idea that the Mail would be scared to print that like.
