Jiah's family members, who found the note at their house, preferred to retain the original doubting police action, but has agreed to give notarised copy to the investigators, a police officer at Juhu police station said.
The gist of the note, which is yet to be received by police, reveals the strained relationship of the actress with Suraj Pancholi, son of actor couple Aditya Pancholi and Zarina Wahab, the officer added.
Police will also take the help of handwriting experts to find out whether the letter was indeed written by Jiah herself, though the family claims that it was her handwriting.
According to reports, the note says, "You have cheated me. I trusted the relation. You didn't care about the relation. By the time you will be reading this letter, probably by then I won't be there in this world."
