Turkey has launched an international manhunt for the founder of a major cryptocurrency exchange who stopped paying clients and has disappeared.

The Turkey Justice Ministry is seeking help from Interpol to help find, arrest, and return Thodex CEO Faruk Fatih Ozer from Albania to Turkey, per state-run media.

In a statement from an unknown place on Thursday, Ozer promised to repay investors and to return to Turkey to face justice at a later date. The government has blocked company accounts and police raided the office in Istanbul.

In a Bloomberg report, losses are estimated to be as high as $2 billion, invested by 390,000 active users.

Thodex lured investors in with the promise of free DOGE coin, but has yet to pay that out either.
