The Nigerian government has dropped money laundering charges against a Binance executive.
Tigran Gambaryan, head of financial crime compliance at the cryptocurrency exchange, was detained in February.
He and Binance were accused of laundering $35 million, but both denied the charges.
The charges were withdrawn due to Gambaryan’s deteriorating health, according to the state-run News Agency of Nigeria.
Nigerian authorities have placed restrictions on cryptocurrency exchanges to stabilize the naira currency.
In response, Binance halted its operations in the country earlier this year.
Separate charges against Binance remain under investigation, with a trial set for next month.
Neither Binance nor the anti-graft agency has commented on the matter.
