An order has been given by Justice Taiwo Taiwo unfreezing the bank accounts of Bamboo Systems Technology, Rise Vest Technologies and four other companies.

According to the apex bank, it wanted to probe the source of forex used by the firms to buy foreign securities and cryptocurrencies.
Justice Taiwo ruled that the central bank’s order relied on a circular to banks, which was not supported in law.
“The interim order freezing the accounts of the (companies) is hereby vacated,” Taiwo said.
Taiwo ordered Zenith Bank and Guaranty Trust Bank, which hold accounts for the companies, to “immediately unfreeze” the accounts and grant them “unfettered access” to the accounts.
In February, the central bank barred financial institutions from dealing in or facilitating transactions in cryptocurrencies.
