The "Bobby" actor took to Twitter to warn his fans to steer away from fake accounts in Ranbir's name on the micro-blogging site.
"Hello friends. This is Ranbir's dad. Just want to state that he's not on any social platform whatsoever so please don't get fooled by any dupe," Rishi tweeted.
Social media went into a tizzy when the "Barfi!" actor hopped on to the virtual platform wagon for a promotional activity earlier this year.
The cinema icon followed the post by another stating: "That message was important to those fans of his who still believe that he is on Twitter. I get requests and complaints regarding him. Sorry!"
The 62-year-old, who was seen in "Do Dooni Chaar" and "Student of the Year", also walked down the memory lane and shared some photographs of a sweater.
He reminisced: "Sweaters. It was a passionate collection, over a period of time, which I used in films without repeating. This info for fans inquiring about it."
