if your previous employer is contemplating to file a criminal case against you or your pseudo firm, then you will have to take anticipatory bail, if not you could be arrested along with your father and thereafter if you or your father wish to obtain bail, it might become difficult.
Regarding the complaint itself, other than your phone number and house address, there is no other directly implicating documents or proof with this employer, hence the complaint eventually will get dismissed. If the employer is not having proof or documents then in my opinion he might not even file the complaint.
