Since last week we have spoken to a significant number of people, some who have previously featured in the inquiry and some who have not.
We have now undertaken a forensic search at an address on All Hallows Road.
It has been nearly seven years since Paige disappeared and in that time forensic techniques have become more and more advanced.
In particular, DNA testing and analysis has become more sensitive and I am hopeful that this will assist in the work that is being undertaken today.
