Filmmaker Karan Johar on Friday said that he did not personally know two people being probed in a widening investigation into drug abuse allegations in Bollywood, refuting media reports that described them as his "aides". "Several media/news channels have been airing news reports that Kshitij Prasad and Anubhav Chopra are my 'aides'/'close aides'. I would like to place on record that I do not know these individuals personally and neither of these two individuals are 'aides' or 'close aides'," he said in a statement.
