Tigran Gambaryan, a former US federal agent focused on crypto, and Nadeem Anjarwalla, a second Binance executive, have been detained in Abuja without their passports for two weeks. In related news, Changpeng Zhao, the former CEO of Binance, has been ordered by a US district court to surrender his Canadian passport and remain in the US until sentencing. This decision comes amid concerns from US Justice Department prosecutors regarding Zhao's substantial assets and ties to the UAE, a country without an extradition treaty with the US. Additionally, Binance's Nigerian operations face challenges as the government has summoned CEO Richard Teng. Amid these developments, Binance has hosted a virtual assets law enforcement workshop for officers of the Keelung District Prosecutors Office in Taiwan, demonstrating a commitment to building a trusted Web3 ecosystem.
