Whenever an FIR is lodged the police officer sends a report to the concerned Magistrate under Section 157 of the code of criminal procedure.
You can get the information about the FIR from the district civil court. You should file a questionnaire in the registry section (najarat) of the district civil court along with requisite court fee.
Next day the najarat will answer your question and also provide the FIR number if any first information has been lodged against you.
