“My brother told me that after I finished my work, he will open shop for me. That was why I came to Edo.
“I was not the one with explosives. It was my brother. I was never at home. I used to go to Auchi to look for shops.
“I was at home when he asked me to burn gas in his farm because he wants to harvest cassava. I told him I cannot do it so he asked Sanusi to go and help me.
“I only heard explosion at my back and Sanusi died. I only know about Sanusi and another man that used to visit my brother. Sanusi resides Okpella. They never sent me anywhere. My brother told me he is a driver.
“I just discovered that the car belongs to him. I visited markets not to look for targets to bomb but to search for any empty shop I can rent.
“When I became aware that my brother was manufactureing explosives, I started looking for ways to leave the house. I ask him about it and he told me to shut up. He does not do it at home. I learnt about it four weeks ago. I saw them taking explosives out one day. I did not know where they took them to. He has a secret room which he locked up. Nobody enters the place.”
Wife of the fleeing suspect, Zainab Ibrahim said she wanted to cry out when she learnt about the explosives.
“My husband is a driver that takes passengers to and from Abuja. I don’t enter the private room in the house.
“When I know about the explosives, I asked him about it, he said he was not the owner or manufacturer. I wanted to shout out. I was sleeping when the one that killed Sanusi exploded.”
