Lagos - Nigeria's military says it has busted a terrorist intelligence cell and arrested two women and a businessman who "actively participated" in the April abductions of more than 200 schoolgirls.
It was unclear if the arrests might help in rescuing at least 219 girls who remain captive.
A statement says businessman Babuji Ya'ari belonged to a vigilante group fighting Boko Haram Islamic extremists as a cover "while remaining an active terrorist."
It accused Ya'ari of "coordinating several deadly attacks" since 2011 in Maiduguri in northeastern Nigeria, the birthplace of Boko Haram.
The Defense Ministry statement Monday said his detention led to the arrests of two women, one an armorer and spy, the other a paymaster.
Boko Haram is behind a 5-year-old insurgency that has killed thousands of Muslims and Christians.
