Senior special assistant to the president on media and publicity, Mallam Garba Shehu has said that an audio recording allegedly of Leah Sharibu is being analysed by the Department of State Services (DSS).
This he said when responding to newsmen report on how Leah who is in custody of the Boko Haram insurgents appealed to President Muhammadu Buhari.
Recall Sharibu was kidnapped alongside 118 students at Government Girls Secondary School, Dapchi, Yobe state, in February.
The kidnapped girls were subsequently released, except five that died while in detention.
Sharibu was withheld after she refused to renounce her faith.
The Islamic State West Africa Province (ISWAP), a breakaway faction of Boko Haram, has kept her in captivity for seven months, sparking public outrage.
Shehu said Buhari’s administration would launch swift action briefings from the DSS on the audio.
“We are aware of the audio in circulation concerning the unfortunate situation of our daughter, Leah Sharibu,” he wrote on Twitter.
“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.”
