The bandits were said to have broken into the academy around 1 am on Tuesday.
Military sources who spoke with TheCable said two officers were killed and while two others were abducted in the attack.
”On 24 August 21, at about 0125hrs, bandits in their large numbers attacked NDA Afaka and kidnapped 1 Offr; Maj Datong while Lt Cdr Wulah and Flt Lt CM Okoronwo were shot dead. 2Lt Onah sustained gun shot injury and currently receiving treatment at own hospital in NDA,” a source said.
Another source said: “They came in, silently, through the part of the academy where we have barbed wire and not properly fenced. Unfortunately, there were no soldiers on guard duty at that end. So, the bandits sneaked in, through to where the officers were and got three of them.
“It was when they shot one of the officers that everybody woke up, and before we knew it they had made their way outside and fled.”
“The attack is a big slap on our face. How could we have allowed that? They already knew there was no guard on duty and came in through that axis.”
TheCable understands that the academy authorities will subject some soldiers to court martial for failing to secure the area.
Onyema Nwachukwu, army spokesperson, did not immediately respond to a message seeking his comment on the incident.
In the recent months, communities in Kaduna and other parts of the north-west have been attacked by bandits.
The bandits had also attacked some schools in the region, and abducted many students.
