Detained US Binance executive Tigran Gambaryan had to be wheeled into a courtroom in Abuja, Nigeria, today after a herniated disc in his back left him in severe pain and "barely able to walk", his family reported on Monday. Since his detention in Nigeria in February, Gambaryan's health has continued to deteriorate. At first, Gambaryan was placed under house arrest, but after his colleagues escaped, he was transferred to the notoriously dangerous Kuje prison, which houses violent criminals, including members of the Boko Haram terrorist group.
