Is there evidence that even one biolab was found?

The DoJ press release uses that term, but it and the criminal complaint describe a factory for counterfeit diagnostic tests, which does not actually involve any biological research or other activities.

The other links you give are strongly partisan sources, and the last one is pretty flagrantly making things up: if the government arrested somebody for an illegal biolab and found vials labelled "Ebola", why would they leave that out of the criminal complaint?

Maybe because they didn't want the publicity or attention as a discovery of that nature would be very embarrassing for the FBI and other agencies. As I remember the media didn't make much of an effort to cover this story. Hmmm..

Why didn't our mainstream media report on this story?? They did at first but then a command from very high up was given to all media outlets to drop the story and be silent. We all know that mainstream media is consolidated into a couple major corporations, so yes, that is a very probable scenario.

My theory is that Biden's advisors were fully aware of this lab or the existence of it at least and they unexpectedly got caught by a health inspector.

If they were trying to hush up a biolab, it would be weird to put "biolab" in the headline of the press release. To the contrary, the government loves to make the biggest possible deal out of whatever indictments they can make. Any lurid detail they could back up in court would be in the complaint.
