Binance CEO Richard Teng has demanded the release of the exchange's executive Tigran Gambaryan from detention in Nigeria, where he has been held for more than 70 days.
In a blog post, Teng said that Gambaryan's detention "has set a dangerous new precedent for all companies worldwide," adding that he "is innocent and must be released."
Gambaryan, the exchange's Head of Financial Crime Compliance, was detained in February by Nigerian authorities alongside his colleague, Binance's regional manager for Africa Nadeem Anjarwalla. The pair had traveled to the country to liaise with officials as they conducted an investigation into crypto exchanges.
Both Binance execs were initially held without charge under the terms of a court order, before Anjarwalla escaped what Teng characterized as "unlawful detention". The pair, along with the exchange, were subsequently charged with tax evasion by Nigeria's Federal Inland Revenue Service (FIRS), while Gambaryan was transferred to a jail run by the country's anti-corruption agency.
According to local media, Nigeria is seeking the extradition of Anjarwalla; a spokesperson for his wife subsequently claimed that reports of his arrest in Kenya are false.

Detained Execs, Daring Escapes: How Binance's $35 Million Battle With Nigeria Unfolded
Binance’s operation in Africa's biggest cryptocurrency market is under intense scrutiny, with Nigerian authorities accusing the crypto giant and a host of other exchanges of infractions including currency manipulation and facilitating transfers of illicit funds. With one Binance executive in custody in Nigeria, and a second having fled the country after having been detained, Nigerian authorities have singled out the exchange for circumventing Nigerian laws and for tax evasion. According to court...
In his blog post, Teng emphasized that Gambaryan was visiting Nigeria as a "functional expert in financial crime and capacity building in policy discussions," and did not go to the country as a "'decision-maker,' nor a "negotiator.'"
The Binance CEO also published a detailed breakdown of the exchange's activities in Nigeria over the past two years, and its negotiations with Nigerian lawmakers and regulators.
Nigeria is currently undergoing a currency crisis, which Teng claims had been attributed by local authorities to Binance's activities in the country.
As well as pushing back against those claims, he alleged that Gambaryan, an "innocent, mid-level employee," is being held in "a dangerous prison in order to control Binance." Gambaryan has sued the Nigerian government for violating his fundamental human rights.

Detained Binance Exec Sues Nigerian Goverment Over Human Rights Violations
A Binance executive detained in Nigeria has sued the government for violating his fundamental human rights. According to local publication Punch, Binance's Head of Financial Crime Compliance Tigran Gambaryan has filed a motion with the Federal High Court in Abuja, seeking a declaration that the seizure of his passport contravened Nigeria's constitution. Gambaryan has also asked that the Office of the National Security Advisor (ONSA) and the Economic Financial Crimes Commission (EFCC) be compelle...
Teng claimed that Gambaryan and Anjarwalla had "received multiple assurances that they would be granted safe passage for their meetings," and that in the course of a "hostile" meeting, members of Nigeria's Economic and Financial Crimes Commission (EFCC) demanded that the exchange delist the Nigerian naira from its platform and "provide granular-level detail on all Nigerian users."
Following their detention, Teng said, Gambaryan and Anjarwalla were subject to "aggressive behavior" and were personally accused of "holding responsibility for the state of the naira and the overall economy," as well as allegations of terrorist financing and money laundering.
Decrypt has reached out to the EFCC for comment and will update this article should they respond.
As a "good faith gesture," Teng stated that Binance had delisted the naira and disabled its P2P product for Nigerian users, and urged the country's authorities to release Gambaryan and continue its "engagement" with the exchange over tax liabilities and cooperation with law enforcement.
"I hope that my next update is one where our employees are safe at home with their families," Teng added.
