Firstly, send him a legal demand notice immedietely. If that also not works, file a case against hime for arrears in salary and also claim damages.
First issue a legal notice to your employer narrating all the details and ask him to pay the arrears of salary. If no reply given by your ex employer then you may file a Civil Suit in Local Court.
Draft effective petitions/legal notices will be prepared by me on nominal professional fee.
