Nigeria's secret service has arrested the spokesman for Boko Haram who frequently made statements to the media after attacks by the radical Islamist group, according to security sources.
Abu Qaqa was held in the northern city of Kaduna in the early hours of the morning, the State Security Services (SSS) source told the Reuters news agency on Wednesday.
"We are still taking to him. Since 'Abu Qaqa' is a pseudonym for the Boko Haram spokesman, we want to be sure of who we have with us. But we have been on his trail for months now. He's been changing locations and contacts," the source said.
Ahmed Abdullahi, the Borno state director of the SSS, told the Associated Press on Wednesday night that they had arrested found the man by tracking his mobile-phone signal.
