Enforcement Directorate seeking custody.

Dear Sirs/Mams, I am a CA by profession & my query is for an economic offence by my company for which I am part of 3.5 yrs back myself along with the directors of the company were arrested for tax fraud & money laundering, being the only woman in this case luckily I was granted bail next day. An Inquiry has been in progress & In the chargesheet I have been also accused. The case has moved to the Supreme Court and we have no relief, recently all our assets / bank accounts frozen. Court ordered re-investigation & ED has called me for questioning a number of times. I had to admit a few things with some concrete evidence against me. It has been a big fraud by this Company(not willing to share the name as it has been in the news already). The directors have spent a substantial amount of time in Custody. The Latest is that ED is planning to take custody of all including me following raids in office/ seized documents & office also seized. As per my lawyer I must be ready for ED arrest anytime since AB already rejected long back. Wanted to know what is ED custody & where will they keep me & in how much time can I get bail. Is there any way I can prevent arrest? If ED gets custody, will it be a stringent interrogation & how will they treat me? With no relief from court, what shall I be prepared with for ED custody?
