Shit, this doesn't sound good. As others have stated, I just hope it has to do with dodgy trading of the company's shares, not anything dodgy by the company itself. I'll be holding my breath for a while I think.
Thankfully I sold a big parcel a few weeks ago at $1.65, so I've locked in a ~300% return even if it goes to zero (not suggesting it will, just to be clear).
