A second schoolgirl from the more than 200 seized in the Nigerian town of Chibok has been found, the army says, said BBC.
But a spokesman for the Chibok girls' parents has cast doubt on the claims, saying that the girl's name is not on the families' list of those missing.
An army spokesman said 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.
In all, 218 girls remain missing after their abduction by the Boko Haram Islamist group from a secondary school in north-eastern Nigeria in 2014.
