Do Kwon, one of the founders of Terraform Labs, is reportedly in Serbia after leaving Singapore and Dubai.
The South Korean Ministry of Justice is attempting to contact the Serbian government for aid in extraditing Kwon back to South Korea, as the two countries have signed the European Convention on Extradition.
This comes after the collapse of the Terra ecosystem and the subsequent investigations and lawsuits that followed.
Kwon has had his passport rendered invalid, making it extremely difficult for him to travel.
Prosecutors allege that he is fleeing to avoid an inquiry, though he has denied this allegation in the past and has been seen on social media sporadically.
He has been issued an arrest warrant, which has been shared with Interpol and resulted in a red notice being released.
