Fearing evidence is being tampered with in the ongoing investigation of Sushant Singh Rajput death case, his sister Shweta Singh Kirti has penned an open letter this morning to Prime Minister Narendra Modi, requesting him to intervene.

Shweta posted the letter on her verified social media accounts. The letter reads: "Dear sir, Somehow my heart says that you stand with and for the truth. We are from a very simple family. My brother had no godfather when he was in Bollywood nor do we have anyone right now. My request to you is to immediately look into this case and make sure that everything is handled in a sanitized way and no evidences are tampered with. Expecting justice to prevail."

The open letter to the Prime Minister comes a day after her post where she shared her late brother's hand-written plans for himself on a whiteboard, which reveals that the actor was planning to start transcendental meditation from June 29.

Shweta shared a photograph of a whiteboard, on which, in Sushant's handwriting, is a daily to-do list for himself. The list, aside from his plans to practice transcendental meditation daily, includes other instructions like, "make your bed after waking up, read books, watch content movies/series, learn guitar and workout," among other things.

Sushant Singh Rajput was found dead in his Mumbai residence on June 14.
