He said that he lost his right leg in an attack at Konduga, Borno State but continued with the Boko Haram because he was brainwashed.
“Abu Hafsat, a Boko Haram commander, and I led other squads to abduct the Chibok girls. We led the operations to invade Gwoza, Bama, Limankara mobile barrack, Bita, Bosso, Madagali, Chibok, Pulka, Firgi, and Mubi.
“In Madagali which was my home town, Adam Vitiri, Abu Adam and Habu Kudama, some high ranking Boko Haram Commander and I led an operation in 2014 where we killed some students and youths at the Central Secondary School in Sabon Garin Madagali.
“In one of the operations, I abducted my wife named Maryam who had two kids for me in Sambisa Forest.
“It is unfortunate that I was brainwashed and misled not only on some abductions but in the killings of my own people that were innocent. I wholeheartedly regret my actions.
“During a battle in Konduga Boko Haram commanders and I led the operations, I lost my right leg and was almost got burnt. Even at that, I did not stop fighting for the cause. Sheikh Shekau ordered that I should be given a tricycle which I continued to use for various operations before I eventually surrendered.” He was quoted as having said.
He said that he had to surrender to the military because he was tired of the senseless killings with the members resorting to stealing and acts opposed to the teachings of Islam.
He recalled that women were being raped in public, children starved to dead and many dying daily.
“I willingly surrendered to the military because I was tired of the senseless killings and fights. I realised that our people have resorted to stealing and all sorts of atrocity contrary to the teachings and practice of Islam.
“Women were being raped, sometimes publicly. Children died from malnutrition and disease as the living condition became harsher. As there was no food in the camp, people died every day because of hunger.
“I will continue to cooperate with the security agencies in providing useful information on our mode of operations and to disclose top-secret hideouts of our commanders.”
