The Presidency on Monday acknowledged that there was an audio recording purported to be the voice of Leah Sharibu, the lone Christian girl still in Boko Haram captivity after herself and her school mates were abducted in Dapchi, Yobe state, in February.
One hundred of them were later set free while five were reported to have died.
Leah was however retained by the terrorists for failing to renounce her Christian faith.
An audio tape was, on Monday, published by an online medium in which she asked President Muhammadu Buhari to have pity on her while also calling for assistance for her family.
Reacting to it, Senior Special Assistant to the president OJ media and publicity, Garba Shehu, said in his Twitter handle, @Garshehu, on Monday that the “secret service” was analyzing the audio.
He promised that the president would spare no effort to ensure all the girls in Boko Haram’s captivity are freed.
He tweeted: “We are aware of the audio in circulation concerning the unfortunate situation of our daughter, Leah Sharibu.
“In dealing with terrorists, nothing is too trivial.
“The secret service is analyzing the voice.
“Our reaction will follow the outcome of the investigation.
“For President Buhari, nothing will be spared in bringing all our girls home. He will not rest until all of them are freed.”
