The remaining members of the family believed to have fled to Syrai say they are "devastated" by their disappearance.
Bedfordshire Police issued the following statement on their behalf:
We are devastated by the disappearance of these 12 and are very concerned for their safety.
This is completely out of character and we are very worried of the danger they may now be in.
Muhammed Abdul Mannan is elderly and both he and Minera Khatun have health issues.
This just does not make any sense. We can only think they have been tricked into going there, it is no place for elderly or young people.
We would urge any of them to please make contact with us or the police to let us know they are ok.
