No coins were sequestered by the authorities.
My BTC balance was always correct at bitcoin-24. ( I didn't look closely enough at the fiat side to be able to say something about that )
After BTC withdrawal was enabled again the balance was still correct. I requested a withdraw of the full amount and got it a day or two later.
A few had the nerve to do test withdrawals with 0.1 BTC in this situation and complained that further withdrawals were delayed.

I think most people got their BTC out.
The last ones were supposed to contact the lawyers of bitcoin-24 directly to get their case resolved.
