Gunmen suspected to be members of the Boko Haram yesterday attacked and killed the Comptroller of the Nigerian Customs Service (NCS) in charge of Borno and Yobe States Command, Alhaji Adamu Ahmadu. Ahmadu’s death however came on the heels of an outcry by the Christian Association of Nigeria (CAN) in Abuja, warning that if the sect’s attacks on Christians and their institutions continue, the nation’s unity would no longer be sustained. However, investigations revealed that Ahmadu was killed in his country home, Potiskum, one of the largest town in Yobe State at about 7 pm. It was gathered that about four gunmen invaded his house and shot him and some other persons. Eyewitnesses said the gunmen came in and forced their way into the house shooting sporadically until they got the new Comptroller of Customs who was newly posted to take charge of the Borno/Yobe States command. A reliable source within the Security circle confirmed the incident to journalists on phone last night. THISDAY had to make calls to confirm the incident when the rumour filtered into town that the Customs boss was gunned down last night. The Borno State Police Commissioner, Mr. Simeone Midenda, who seems to have no prior knowledge of the killing was shocked to hear the information when he was contacted on phone for confirmation. He just simply said: “My brother, I have not gotten this but please let me find out, thank you.” In a similar incident, four persons were shot dead by some unidentified gunmen in Maiduguri yesterday. The four persons according to witnesses in Mafoni Ward of Maiduguri where they were killed were said to be mostly Igbo speaking tribesmen. Eyewitnesses said they were killed at about 5:30pm when gunshots were heard coming from the area. The Public Relations Officer (PPRO) of the state police Command, Samuel Tizhe, who was contacted on phone to confirm the incident to journalists, said though he was aware of the attack and alleged killing, he could not give details on the matter as such attacks fall within the jurisdiction of the Joint Task Force (JTF). The JTF operatives also were not forthcoming in providing information on the matter as most of them insisted they were not aware. Meanwhile, while addressing journalists at the Christian Ecumenical Centre Abuja on the ongoing onslaught, CAN President, Pastor Ayo Oritsejafor, observed that what the body found most worrisome was the absolute lack of security. “The implications of an insecure nation need not be over-emphasised. What is at stake is the need for Christians in Nigeria to be free to practise their religion wherever they are,” he said. While accusing the Federal Government of doing little to quell the attacks, Oritsejafor said: “What we have so far witnessed in the few months in the first threat is enough for CAN to warn that if the so-called Boko Haram makes good its latest threat, Nigeria may never be the one and united country that we know. “Our concern is not just about the terrorist methods, but their views. Our concern is not just about their barbaric acts, but their ideas. This is why we call on peaceful Muslims to rise up against the so-called Boko Haram. To the federal government, we say the time for action is now. Stop the foot-dragging and pampering of the sect members. This is the hour for courage,” he said. He further urged members of the National Assembly to ensure that ongoing probes carry the full weight of punishment for those found guilty. "Those probing the oil subsidy issue must not compromise,” Oritsejafor said. "They must be made to account for all their misdeeds in the oil industry.” CAN also informed journalists that the incessant cases of Boko Haram attacks may not be unconnected with the polarisation of the security agencies. “What we know is that what security agencies are doing is inadequate,” the group said. “They don't have enough means of gathering intelligence, including the fact that security agencies are polarised along religious lines.”
