1) My sister had a friend. Their friendship ended in January 2012 after which this guy continued to follow her for a year upto July 2013.
2) He wrote several emails to her, threatening her, stalking her to her office and even hacking her email account
3) We reached out to the parents of the boy after which he stopped doing his things end of July 2013.
4) We have on record all his emails he sent before July 2013. He never emailed or called after that.
5) All of a sudden some calls went to my sister's office in London (alleging her of tax evasion).
6) There is truth to the tax evasion story. She did some tax evasion and had also involved one of her senior office colleague when she was in India in 2013.
7) She wrote to him on email about details of that tax evasion scheme. Apparently, this guy had the hacked email and hence he gave the date of that email to the HR office in London of my sister.
8) I believe he was waiting for the limitation period to get over (3 years for stalking crime).
9) So our question is, have we lost a right to file an FIR as we dont have any evidence post July 2013.
