Karnataka Home Minister Dr G Parameshwara has said that the decision to arrest JD(S) MP and prime accused in the sex video case, Prajwal Revanna, at the airport upon his arrival in India will be taken by the Special Investigation Team (SIT). Prajwal Revanna is the grandson of former PM Deve Gowda. He is accused of sexual assault on several women, also videographing them wihout consent and he faces arrest when he returns to the country. All this comes a day after Prajwal Revanna released a video claiming that he will appear before the SIT and join the investigation on Friday. The home minister also reminded that Prajwal's Revanna documents - remember he is on a diplomatic passport -- will expire on May 31. If he loses the election, he will lose immunity and automatically his diplomatic passport will be seized, that is what the home minister said today.
