Golden Finance reported that Tigran Gambaryan, a Binance executive in poor health, pleaded with a Nigerian judge on Monday to allow him to undergo back surgery because he suffers from a herniated disc. "I have been complaining about this problem, but it has never been resolved," said Gambaryan, 40, as his money laundering trial in Abuja, the capital of Nigeria, continued. "Due to the lack of proper treatment, my nerves have been permanently damaged, which is why I am in this condition now. I can no longer walk," Gambaryan added, limping into the court after being denied the use of a wheelchair. Gambaryan has denied the prosecution's charges since he was imprisoned in a prison near Abuja in April, but he has been suffering from pneumonia and malaria.
