A former employee of Alpha-Beta Consulting Limited has lodged a detailed petition accusing the tax-revenue consultancy widely reported to be owned or linked to President Bola Ahmed Tinubu of forgery, workplace harassment, discrimination, and improper cybersecurity policy manipulation during his tenure. The allegations, which have been submitted to the Nigeria Police Force, the Independent Corrupt Practices and Other Related Offences Commission (ICPC), and the Economic and Financial Crimes Commission (EFCC), allege misconduct at the highest technical levels of the firm.
Segun Oluwasanmi, who worked at Alpha-Beta from September 2018 until his voluntary exit on January 7, 2025, claims that in September 2023 the company’s Chief Technical Officer (CTO), Olumide Hezekiah Idowu, forged his signature on the firm’s updated Cybersecurity Policy without his knowledge or consent. According to Oluwasanmi, the signature appeared on the document dated September 8, 2023 and was submitted to the firm’s Managing Director for final electronic endorsement effectively altering official records.
Oluwasanmi alleges the forgery followed months of alleged workplace marginalisation and harassment by the CTO, including repeated exclusion from the cybersecurity policy review process despite his professional role. He said internal complaints to management and even to the CTO himself were ignored, and a panel established to investigate the forgery never released a formal report or took corrective action.
In his petition — filed through the Lagos chapter of the Committee for the Defence of Human Rights (CDHR) — Oluwasanmi argues the CTO deliberately deleted most of the collaborative comments he and his team submitted to the draft policy, reallocated roles and responsibilities, and inserted his signature in a manner he described as criminally fraudulent. The petition cites provisions of the Cybercrimes (Prohibition, Prevention, etc.) Act, 2015 and the Criminal Code Act regarding forgery, electronic signature fraud, and unauthorized manipulation of data.
Oluwasanmi also emphasised his professional contributions to the firm, including drafting and implementing multiple key governance documents such as the Change Management Policy, Procurement Policy, Inventory Policy, and Business Continuity Plan, asserting that his exclusion from the process was retaliatory in nature and part of a broader pattern of harassment dating back to 2022.
According to the CDHR petition, the case was first raised internally in 2023 and followed up verbally and via email multiple times including in June 2024 and December 2024 but without resolution. Oluwasanmi claims that even when the internal panel was convened in September 2023, the CTO allegedly admitted his actions under informal questioning, yet management took no public or documented corrective action.
The petition urges a thorough, independent investigation by law-enforcement agencies into the alleged policy forgery and associated workplace harassment, stressing that failure to act would undermine corporate governance and weaken the integrity of the firm’s cyber-security framework a sector of growing importance in modern corporate and public-sector operations.
As of this reporting, Alpha-Beta Consulting has not publicly responded to the allegations. The unfolding complaint adds to ongoing scrutiny of Alpha-Beta’s operations, which have previously been the subject of other whistleblower claims alleging tax irregularities and labour disputes.
