Received SCN on Police Verification of Passport after travelling to abroad

Hi there, My wife received the Fresh Passport under Normal type but Post police verification status. Date when passport received : 17 July 2017. I was waiting for police officers call for police verification but I never get any call for couple of months. Then I personally visited (in sept.) the Police station (Lonikand, Pune) to check whether they received my wife's passport file or not. The police officer said that they have received the file and called my wife for police verification with required documents. We both visited the police station again and provided all documents and completed the formality of police verification and also he asked for 500 rs as fee. I paid the same. Later we happily left the station and all done and I started the Visa process for my wife. Visa process also completed in October. We both traveled to Canada at 4th March 2018. Now after travelling to Canada I received the Show Cause Notice from passport office saying 'As per police verification report you were not available at address mentioned in application' and also written that if I don't reply within 15 days then they will initiate the passport impound process. :( As we already completed the police verification don't know how comes the report says we were not available at address, and that too after long time. Problem is we are now in Canada. So need your help on what need to do in this case? Shall we seek for help from Indian Embassy in Canada? Please help me in this issue, thanks a lot in advance. Thanks, Manoj
