Your case is an example of ignorance of law. Ignorance of law cannot be claimed as exemption from the offence. What you have stated that you were told by the accountant to pay to some totally irrelevant persons that too an amount of Rs. 5 Lakhs is unbelievable. Even an uneducated person will have his own doubt,whereas you have take the appointment after passing various skill tests and examinations, interviews, so it appears to be folk tale narrated here.
No doubt the accountant will also be held for having passed it, whereas it was your duty to confirm the person receiving the money, that too it is ridiculous that payment for 25 crossed cheques were paid to only two individuals. This can be considered as a high handed and well planned scam,cheating and conspiracy.
You wait for the summons from police and sooner you get one, you may apply for anticipatory bail, get enlarged on bail and then contest the case before the trial court on the basis of merits in your side.
