Goni, who is undergoing rehabilitation at a military detention camp in Maiduguri, said this in an interview with the News Agency of Nigeria.
The former Boko Haram commander is an indigene of Bama in Borno State. He surrendered to the military in Cameroon after he escaped from the Sambisa Forest eight months ago.
He claimed to have held several positions in 10 different cells of Boko Haram in Sambisa.
Goni said the last position he held was as the Chief Officer of Dispute Resolution for the group.
He explained that many militants came to him to settle problems ranging from family matters. He also reconciled Boko Haram factions.
“I rescued people sentenced to death and minimised punishment of those who committed crimes. I was one of the most influential persons in the group and they always listened and abided by what I said.
“I joined Boko Haram because of the condition I found myself in the last five years. When the insurgents invaded Bama town, I ran with my family to Cameroon thinking I was in a safe destination. But on reaching Cameroon, I was shocked to realise that I brought myself into another Boko Haram camp. By that time, I knew I would not survive without joining the group.
“Days after my induction, we opened a permanent camp at the Cameroon border and named the forest “Aluska.” It was in that camp that I learnt all types of training including handling weapons.
“After the training, we embarked on our first mission. We invaded a military formation in Cameroon, dislodged the soldiers and took many weapons from their armoury. We couldn’t take any vehicle because the area was surrounded by a river.
“We took the weapons we recovered to our leader Abubakar Shekau and briefed him on our success. He was happy that five of us could dislodge a military formation. After congratulating us, he appointed me to lead the group and returned our weapons to us.
