One among the girls, Halima Ali is said to have been married off to a Boko Haram commander after their kidnap.
A statement made available to newsmen by Emmanuel Ogebe of the US-Nigeria Law Group (USNLG) on Friday, revealed that Mr Maiyanga communicated his daughter who escaped with others on Thursday.
Naija News understands that the insurgent during the 2014 attack took away two daughters of Maiyanga.
However, the children are said to be with the army and anxiously waiting to identify with their parents.
“Today, a parent of still missing Chibok schoolgirls who USNLG supports informed us of the escape of additional schoolgirls six years and nine months after their abduction,” Ogebe revealed.
“We spoke and confirmed from Mr Ali Maiyanga moments ago that he in fact spoke with his daughter today who informed him that she along with others were rescued. Her sister who escaped four years ago and is on break was overjoyed at the news of her sibling’s escape,” the statement added.
