In a letter dated August 6, 2025, Sterling Bank responded to complaints from Adejumo’s legal team, revealing that the issue was caused by another customer who shares his full name and accidentally submitted Adejumo’s personal email while opening a bank account.

The issue was first reported by the Foundation for Investigative Journalism (FIJ) on July 18, 2025.

The report disclosed that Adejumo who has never been a Sterling Bank customer received a notification that a new account had been opened in his name on July 9.

Within days, he was bombarded with eight different email verification alerts, sparking fears of identity theft.

Even more troubling, a ₦5,000 deposit and withdrawal were made on the account the same day it was opened, by someone identified as LEGBETI Anuoluwapo Valerie.

Despite public outcry and repeated attempts to contact the bank, Sterling Bank remained silent for three weeks before finally responding.

The August 6 response blamed the mix-up on a customer error and assured that Adejumo’s email had been permanently removed from their system.

The Sterling Bank data breach has triggered public debate over Nigeria’s KYC (Know Your Customer) processes, with critics pointing to lax verification protocols that could expose citizens to identity fraud and digital intrusion.
