HD Revanna, the father of Karnataka MP Prajwal Revanna, has accused rivals of creating a conspiracy out of "old videos", a comment that is likely to raise a bigger row over his son's alleged link to the obscene videos. A woman yesterday filed a police case against Prajwal Revanna and his father over alleged sexual assault. Prajwal Revanna, the Janata Dal (Secular) MP and grandson of former Prime Minister HD Deve Gowda, has denied the latest allegations and says the videos were morphed. He left for Germany on Saturday morning after voting in the Lok Sabha elections a day earlier.
