Mr Revanna's bail petition will be heard later today.
Hassan MP Prajwal Revanna, who is accused of sexually assaulting multiple women, has been arrested after his flight from Germany's Munich landed at the Bengaluru airport in the early hours of Friday.
The Janata Dal (Secular) leader, who is also the candidate from the Hassan Lok Sabha seat, had left for Germany on April 27, a day after polling in his constituency. Videos allegedly showing him sexually assaulting the women had surfaced the same day.
Mr Revanna, who is the grandson of former prime minister HD Deve Gowda and nephew of former Karnataka chief minister HD Kumaraswamy, was aboard Lufthansa flight LH0764, which landed at the Kempegowda International Airport.
The JDS leader was handed over to police officials waiting at the airport and sources said he will be taken to the Crime Investigation Department (CID) office, where he will spend the night in the custody of the Special Investigation Team probing the case.
A medical test will be conducted and he has to be produced before a magistrate within 24 hours.
The anticipatory bail petition filed by Mr Revanna, which will now turn into a regular bail plea, is also scheduled to be heard today. The verdict on the anticipatory bail plea of his mother, Bhavani Revanna, is also expected today.
