The girls were released on Wednesday morning with about five of them reportedly dead.
In a statement on Twitter by its National Publicity Secretary, Kola Ologboniyan, the party said the release of the girls was a plot by the All Progressives Congress (APC) to gain heroic appraisal from Nigerians.
He wrote “#Dapchi: A poorly crafted tragicomedy lacking intelligence and tact.
“A scam of no equal dimensions the world over. @OfficialPDPNig had repeatedly warned about conspiratorial plots advanced by @APCNigeria interests to gain heroic attainments.
“This time, the plot has failed. It achieved disgraceful, embarrassing and ignoble ends.”
