A security official at a Nigeria college on Thursday dismissed reports that a massacre at a nearby student housing area which left at least 40 people dead was linked to tensions over a campus vote. The official’s comments came after Nigerian police said they had made many arrests over the massacre which saw victims shot or have their throats slit, but offered no clues for what prompted it as questions mounted over the killings. “I have no evidence to link it to the election,” said Shuaib Aroke, deputy registrar at Federal Polytechnic Mubi, where some of those killed in the massacre in the early hours of Tuesday were enrolled. “It is a fallacy,” he said of the supposed link being suggested by some Nigerian authorities. “We are united here at polytechnic,” added Aroke, who said he is currently in charge of security on campus. He however said he had no information on who was behind the killings.
