The Economic and Financial Crimes Commission Monday arrested former Minister of Interior, Comrade Abba Moro, and two others over the 2014 recruitment exercise into the Nigerian Immigration Service (NIS), which led to the death of no fewer than 20 Nigerian job-seekers.
Also arrested by the anti-graft agency were former Permanent Secretary in the ministry, Anaesthesia Nwaobia, and a deputy director simply identified as Ibrahim.
The three were also grilled over the 2015 e-Passport biometric project of the NIS.
There were calls by individuals and groups for the sack and prosecution of Moro following disclosure that 520,000 applicants paid a total of N520million for the tragic recruitment exercise which witnessed stampede in various recruitment centres across the country.
Moro refused to resign, blaming others for the tragedy.
The arrested men may be arraigned in court, according to EFCC sources.
