It pointed out that it was closely following up all the legal procedures in the incident with the concerned authorities.
The Nigerian Minister of Foreign Affairs, Geoffrey Onyeama, confirmed on Sunday that the Sudanese government had communicated the arrest of the principal suspect to his ministry.
The Federal Government had condemned the murder of the diplomat and pledged to would work with Khartoum to arrest the culprit.
The Nigeria Immigration Service in its reaction expressed shock over the incident, adding that the Comptroller-General, Muhammad Babandede,was in high-level discussion with the Minister of Foreign Affairs over the incident.
