On late Bollywood actor Sushant Singh Rajput’s birthday on Thursday, Kangana Ranaut attacked big shots of the Mumbai based film industry accusing them of trying to “ban” the former, who died by suicide in last year, and alleged that “they collectively killed him.” In a series of tweets, Ranaut, who has been taking potshots at the Bollywood industry, said that she regretted not being there for Rajput when he needed help. “Dear Sushant, movie mafia banned you bullied you and harassed you, many times on social media you aksed for help and I regret not being there for you. I wish I didn’t assume you are strong enough to handle mafia torture on your own. I wish ... Happy Birthday dear one #SushantDay,” she wrote on the microblogging site.
