Any credible new source about the arrest?

Honestly, it's my first time hearing about this incident, even when it happened 5 years ago and was bigger that most crypto exchange hacks that have ever happened in this space.

The Bitcoins that were stolen from the mining pool, were they owned by the mining pool itself or the miners had a stake in them? If the miners had a stake, how is it that they didn't make any noise when maybe Lubian stopped payments and shutdown?
