My father had an Indian passport which expired in 1992.?
This similar thing happened to one of my relative. He also lost the passport while shifting from mumbai to his hometown. Than he applied for new passport without stating that he had old one and its lost now. So when he went to passport office he was denied for the new passport and was told to surrender the old one. The only solution to this problem is applying with stating the true fact and lodge a FIR complain even now. That you had lost your passport previously. Copy of FIR is important as hell in this cases. Hope this would be little useful.
