I'm puzzled (and also angry)
I appreciate it is all too easy to vent at other countries perceived injustices in a matter such as this, but the biggest fail I read in that piece was the utter mind-boggling incompetence on somebody's part to get the correct insurance in place. Seriously, you gotta be kidding!!!
The article implies Race2Recovery "ceased trading" (not sure that is the correct terminology for a charity, but whatever) in 2014, but somebody is/was still operating using that name
News Race2Recovery
If it were me, I would be going full on thru The Charity Commission to get the full low down on everybody involved and wherever or not they are still involved and then pointing my legal team at any potential targets uncovered. I appreciate that might involve trampling on previous loyalties but screw that, the guy's liberty is at stake because someone screwed up in spades.
btw...I donated to his fund, so feel free to disagree with me, but get your money in first.
