Pretty standard low-tech-accuracy clickbaity article. I didn't realize Reuters did those, but I haven't paid attention in a while.

So what exactly did they seize? If it wasn't a brainwallet, or was a physical device that they believe had no backups, the story would make more sense. Would have been pretty easy to include that info.

Also, if they have ensured the guy can't access it, like the article says, then this goes beyond seizure. They just want the money for themselves.

It is impossible to ensure the guy can't access it. If he has the 12 word recovery phrase, he can regenerate the private key without needing the wallet.
