Gambaryan, a former Internal Revenue Service (IRS) agent and Binance’s current head of financial crimes, was detained in Abuja in February, shortly after voluntarily traveling to the Nigerian capital at the invitation of the government. Initially, Gambaryan and another Binance executive, British-Kenyan national Nadeem Anjarwalla, were held under house arrest without explanation. But when Anjarwalla escaped in March, Gambaryan was transferred to the notoriously dangerous Kuje Prison, where he has spent the past five months.
