I don't think she would be under arrest. She is probably kept safe or was told to remain silent before the investigation is done. I know it is so kind of backward way of handling the issue. The case would be postponed by the general CCP meeting, and investigation only starts afterwards. She would be questioned maybe, but I am fairly certain she will not face any danger. She may be asked not to give any comment given the investigation. And investigation normally would take some time.
