Interpol has issued a “Red Notice” for Terraforms Labs founder Do Kwon, accused of fraud following the catastrophic collapse of his company's cryptocurrencies in May.

The Seoul Southern District Prosecutors Office announced on Monday that the notice for Kwon was posted after the office requested Interpol's assistance to trace the South Korean national’s whereabouts last week.

A Red Notice request like the one issued for Kwon and five others, including founding Terraform member Nicholas Platias, asks law enforcement agencies worldwide to assist in apprehending a fugitive facing prosecution or to serve a sentence.

Kwon and his blockchain firm have been under investigation for alleged fraud and tax evasion after investors of its cryptocurrencies – TerraUSD and Luna – filed complaints accusing him of carrying out a Ponzi scheme that resulted in the loss of an estimated 60 billion U.S. dollars following the crash of both coins.
