Not much of a story there so I did a bit of looking, here’s a link from another source with a little more info.

Does seem to be reason for worry, but what do you bet he has a “dead man switch” set up, or a mass of data stashed elsewhere with instructions to leak immediately if anything happens...
My understanding is Assange does have a nuclear bomb of information that will be released should he suffer an untimely death.
You made the point I am making. There are more than one individuals who will release if anything happens to Assamge.
