Better wait for another confirmation, their source is a Twitter user that claims:
Montenegrin police have detained a person suspected of being one of the most wanted fugitives, South Korean citizen Do Kwon, co-founder and CEO of Singapore-based Terraform Labs.
I find it a bit weird and stupid for him to use a European airport, despite not being part of the EU Montenegro has a ton of extradition treaties, and with him on the Interpol list, there is no chance they will not deport him. Pretty a stupid move, he should have fled to some south Asian country instead.
I think OP is likely correct because I did a search for it and cointelegraph is up with the news as Do Kwon is being arrested. His arrest is long overdue as he has been on the run for months claiming he is open to any government call in answering any questions as to what really happened to Terra chain and investors funds.
According to the reports, he was arrested at podgorica airport, Montenegro with "falsified documents" so I was wondering why he did use fake documents in traveling if that be the case. I thought he said he was not hiding from anybody and is willing to respond to any call from the government in answering any questions.
