( CNN ) American missionary Phyllis Sortor , who was kidnapped last month by masked gunmen in central Nigeria , has been freed , a U.S. official confirmed Friday . Officials refused to provide details of her release , but said it involved some form of negotiations . Five men abducted Sortor , a missionary from Seattle with the Free Methodist Church , from her workplace February 23 and demanded a ransom of 60 million Naira ( $ 301,500 ) , Kogi state police Commissioner Adeyemi Ogunjemilusi said . Sortor runs a nongovernmental organization that educates nomadic Fulani children , the police commissioner said . Kogi state is located away from the areas where Boko Haram operates , making it likely that the kidnapping is not related to them . But there is the possibility that an offshoot group could have kidnapped Sortor , or that she might be sold to another group .
