A spokesman for the Chibok girls’ parents Yakubu Nkeki has cast a doubt on the claims by the Nigerian military that a second schoolgirl from the more than 200 seized in Chibok has been found.
He said the girl’s name is not on the families’ list of those missing.
An army spokesman, Colonel Sani Usman had said the girl, Serah Luka was among a group of 97 women and children rescued by troops in the north-east.
Islamist militant group Boko Haram has abducted thousands of other girls in recent years, rights groups estimate.
This comes two days after the rescue of the first Chibok girl, Amina Ali Nkeki.
The army has previously given misleading statements about the rescue of the Chibok girls – in its initial statement after Ms Nkeki was found, it used a wrong name.
In a statement, Col Usman said: “We are glad to state that among those rescued is a girl believed to be one of the Chibok Government (Girls) Secondary School girls that were abducted on 14 April 2014 by the Boko Haram terrorists.”
“Her name is Miss Serah Luka, who is number 157 on the list of the abducted school girls. She is believed to be the daughter of Pastor Luka.”
But the head of the group representing the Chibok girls’ parents said their own records did not match up with the details given by the army.
Yakubu Nkeki told the BBC there were four priests among the parents but none with the surname Luka.
Furthermore, the army said Miss Luka comes from Madagali in Adamawa state, but Mr Nkeki said all the abducted girls were from Borno state.
