The Special Investigation Team (SIT), probing the obscene videos case involving JD(S) Lok Sabha candidate Prajwal Revanna, on Thursday issued a lookout notice against him.
The notice was issued at all immigration points across the world.
The development comes as reports said Revanna had fled to Germany, as a huge cache of explicit videos and photographs showing him indulging in the sexual abuse of several women went viral on social media.
Prajwal, the grandson of former prime minister and JD(S) patriarch HD Deve Gowda and son of former minister HD Revanna, is seeking re-election from Hassan on the JD(S) ticket.
The JD(S) MP, who is in the middle of a massive controversy over his sex videos and faces sexual assault charges, has sought seven days to appear before the Special Investigation Team probing his case.
He, and his father, DD Revanna, were issued notices to appear before the SIT for questioning.
The Hassan MP informed the probe team that he is outside Bengaluru.
On Wednesday, Chief Minister Siddaramaiah took a swipe at Union Home Minister Amit Shah's expression of outrage over the case.
Amit Shah on Wednesday said in Hubballi that the "BJP cannot remain with those who commit atrocities against women", referring to the Prajwal case.
Meanwhile, a case has been registered against both Revanna and his son Prajwal at Holenarasipura based on a complaint lodged by their former cook and relative for allegedly sexually harassing her.
She alleged that Prajwal made video calls to her daughter and spoke in an objectionable manner, which forced her to block him.
