Turkish authorities are pushing forward an investigation into the local cryptocurrency exchange Thodex, which abruptly stopped trading last week.

Reuters reported that a Turkish court on Thursday jailed six suspects awaiting trial, including the brothers of the missing CEO and senior officials.

As part of the investigation, Interpol allegedly issued a red notice to Thodex founder and CEO Faruk Fatih Ozer, who allegedly came to Albania. When he was caught by the Red Notice, we have property transfer agreements with most of these countries. “If God willing, he will be arrested and returned,” said Interior Minister Suleiman Soylu.

Local authorities have arrested more than 83 people suspected of involvement in the case amid growing fears that Thodex was a scam after the platform stopped withdrawing cash.

Some suspects have speculated that Ozer’s siblings – Goffin Ozer and Serape Ozer – may have played an important role in Thodex’s business, stating that both own large cryptocurrency assets, according to local news agency Anatolia.

Lake Guven is said to have around TRY 22 million ($ 2.7 million) on two major local cryptocurrency exchanges including BtcTurk and Paribu. Goffin was reportedly the active boss of Thodex despite not having a formal role in the company.

Sera Ozer, the CEO’s missing sister, allegedly had over 120 million lira ($ 14.6 million) in cryptocurrency transactions on her Binance account between 2018 and 2021. She claimed that this account was not hers. Serap allegedly controlled Todex’s financial activities.

As previously reported, the missing Thodex boss fled with $ 2 billion in crypto, but according to recent reports, Interior Minister Soylu revealed the company’s portfolio is $ 108 million.

The news comes as the Turkish government tightens its stance on cryptocurrencies when the country’s central bank officially banned cryptocurrency payments on Friday. Another Turkish cryptocurrency exchange, Vebitcoin, announced last week that it would cease operations due to staff arrests and allegations of fraud.
