Nigeria's intelligence agency on Tuesday, February 9 said it had arrested a recruiter for the Islamic State group, as well as seven alleged members of the Boko Haram offshoot Ansaru, AFP reports.

The announcement comes nearly a year after the leader of Boko Haram in northeast Nigeria, Abubakar Shekau, pledged allegiance to IS leader in Syria and Iraq, Abu Bakr Al-Baghdadi.

The Department of State Services (DSS) said in an emailed statement that Abdussalam Enesi Yunusa was detained in the northern city of Kano on January 17.

His arrest came after intelligence unveiled "his terrorist antecedents and covert drive to indoctrinate and recruit susceptible youths in the country," the statement read.

The DSS described Yunusa as a "recruiter for the Islamic State of Iraq and Syria (ISIS)" and said he was preparing to go to Libya to join an "ISIS terrorist training camp" with at least three others.

The secret police said he told them two other Nigerians were already undergoing training in the north African country, which has slid into bloodshed since the fall of Moamer Kadhafi in 2011.

At least two others, including one from Niger, were "ISIS agents operating in Nigeria and the West African sub-region", funded by an IS "media expert" using international money transfers.

Four others were arrested in Kano on January 22 "while migrating to Libya, with their immediate families, including infants, in a bid to join ISIS", the DSS said.

Two students were arrested a week later, also in Kano, on suspicion of plotting "coordinated lone wolf attacks" on crowded civilian targets in Nigeria, it added.
