The Army made the revelation on Tuesday via its verified Twitter handle.
The former terror kingpin had appeared in many grisly footages showing fighters aligned with Boko Haram, where he slit the throats of prisoners and shot captives after accusing them of being infidels.
The terrorist, Bulabuduwaye and his team of executors had murdered at least 1,000 persons captured and sentenced to death.
Bulabuduwaye was among the commanders, who fled last year’s invasion of the terror group’s stronghold in the Sambisa forest area by a column of Islamic State West Africa Province (ISWAP) fighters, in May 2021 which resulted in the death of Shekau.
“He broke away after refusing to pledge his allegiance to the Islamic State, to form a camp in Kote village in the axis of Banki, where he was hiding with other fighters.
“He also fears battlefield elimination by ISWAP, being one of those fingered to be eliminated for refusing to pay allegiance.”
Meanwhile, the theatre Commander, North-east “Operation Hadin Kai”, Maj. Gen. Christopher Musa, recently said over 79,000 insurgents, comprising combatants and non-combatants, had so far surrendered to the military.
