“The COAS further commended the Commandant NDA, the GOC 1 Division, the Air Officer Commanding Air Training Command and heads of other security agencies in Kaduna State in the ongoing efforts to ensure the safe return of the abducted officer.
“He assured the Academy that the Nigerian Army would also provide the Academy with additional operational enablers to further enhance the security of the Academy.
“The COAS appealed to the Academy staff to remain loyal to the country and not allow the unfortunate incident to deter them from their ultimate objective of grooming officer cadets for the Armed Forces of Nigeria.
“He further enjoined all officers, soldiers and civilian staff in the Academy to remain vigilant, because the fight against insecurity must be a collective effort.
“The COAS avowed that no matter how long it takes, the perpetrators of this heinous act would be brought to justice.
