Wives of five missing engineers petition Tinubu, National Assembly over husbands’ disappearance

The disappearance of five senior engineers from NELAN Construction Ltd. in November 2021—now subject to formal petitions to President Tinubu and Nigeria's National Assembly—represents a critical security vulnerability that has largely escaped international scrutiny but carries substantial implications for European investors funding infrastructure across Sub-Saharan Africa. The engineers vanished while overseeing the Abakaliki Ring Road project in Ebonyi State, a development financed by the African Development Bank (AfDB). Their abduction by armed assailants points to a persistent security challenge that undermines the viability of large-scale infrastructure contracts, particularly in Nigeria's southeastern regions where project supervision requires constant on-site presence. For European construction firms, consulting engineers, and project finance institutions, this incident crystallizes an underappreciated risk category. While political instability and currency volatility dominate investor due diligence discussions, personnel security during project execution remains inadequately priced into feasibility assessments. The AfDB-financed Abakaliki Ring Road represents the type of development project European firms actively pursue—regionally significant infrastructure with multilateral backing and contracted European technical expertise. Yet the abduction and apparent lack of resolution four years later suggests that standard security protocols and insurance mechanisms may prove insufficient in volatile operating environments. The timing is particularly significant. Nigeria's infrastructure sector is experiencing renewed
