90 days later bank account was un froze but I had already been arrested!
I don't see a question here, but you clearly have a mess on your hands. Consult with and get yourself a good attorney.
Information including why the bank froze your account, do you owe the bank money, is the money for the pre-paid tuition in the bank, is it in an escrow account, is needed before an attorney can answer your question. You should seek a criminal defense attorney in your area who is familiar with white collar crime, since I am assuming that you are being charged with defrauding your customers of their tuition.
Nothing in this answer should be construed as legal advise and does not establish an attorney-client relationship without a signed legal services agreement
