Rebel is reporting that Dr Yaniv was "whisked away" through a secret exit. This is likely indicative of an in-custody transport, ie "in the wagon".
Hypothetically speaking, that might happen after an outburst at trial caused the Prosecution to question whether the Accused is well and fit to stand trial for the listed offences.
We'll need to do more background on matter, but this is one distinct possibility.
The following is for demonstration purposes only, so if you want to take it literally, take a break or something. We neither confirm nor deny the supposition that Dr Yaniv is presently in custody. Watch the farm and the feeds, we'll know soon enough.
More information may be added to this blurb as time permits.
