There is no need to fear. If there is any deduction of amount your company wants and they have given any written communication, then just reply in a written communication to them (preferably on email) that if there is any amount pending, then you are ready to pay that amount immediately.
This communication is important to clear your stance and absolve you from any conspiracy. Maximum that your ex-employer can do is to file an FIR of Cheating, Forgery etc., but that cannot directly be of such a level that police would arrest you. Its is only a matter of Rs.1500/- and once you send that written communication, you would be safe.
