Access Bank Plc, Nigeria’s biggest lender, is accused of illegally blocking an account used to promote media coverage of protests against police brutality that recently swept Africa’s most populous country. Gatefield Nigeria Ltd., a public affairs company, filed a case against Access Bank in a federal court in Abuja, the capital, on Oct. 28, accusing the lender of “unilaterally restricting” its account and demanding damages of $262,000, according to court documents. The account was used to raise funds to support independent Nigerian journalists that covered nationwide demonstrations that lasted almost three weeks, according to the firm. “As more people contributed to our efforts, we noticed that we could no longer conduct transactions on the dedicated account we used for this particular activity,” according to Adewunmi Emoruwa, the lead strategist for Abuja-based Gatefield. The lawsuit will test whether blocking Gatefield’s account without a court order was unlawful. There were other allegations by individuals and organizations on social media that their accounts were restricted during the protests for apparently similar reasons. A spokesman for Access Bank said the lender doesn’t comment on its customers to third parties. A spokesman for the central bank didn’t respond to emails and calls seeking comment.
