The Nigeria Civil Aviation Authority (NCAA) has secretly employed over 380 people in the service without due process since 2015, SaharaReporters has learnt. Documents exclusively obtained by Saharareporters show that over 90 per cent of those employed came from the northern region, with President Muhammadu Buhari’s state of Katsina, alongside Kaduna and Kano taking the lion’s share of the scandalous recruitment. Aviation minister, Hadi Sirika is also from Katsina.
