The Chairman, Chibok Development Association, Pogus Bitrus has said that more than 100 Chibok girls abducted and held by Boko Haram are unwilling to leave their captors.
Bitrus said the girls were ashamed to return home because they already have babies for their Boko Haram husbands.
He said the freed girls told their parents they were separated into two groups early on in their captivity, and were told to choose between joining the extremists and embracing Islam, or becoming their slaves.
The latter group – made up of 104 girls – never saw their classmates again.
He said those who chose to be slaves said they were used as domestic workers and porters but were not sexually abused.
That group was said to contain the 21 who were released last week and the 83 who the government are negotiating over.
