Chief Constable Jackie Roberts paid tribute to the enormous effort of the community of Machynlleth and the surrounding areas to the effort to find April Jones.
She said: "The last few days has seen us deal with one of the most complex and fast moving enquiries in the history of our Force and one our communities have never had to face before.
The community of Machynlleth and the surrounding areas turned out in force using social networks to get the message out and appeal for April’s safe return. To see so many people give up their time freely was truly humbling for everyone involved.
I would like to pay tribute to the tremendous effort that has gone into trying to find April Jones this week. I have spent time with the family, and they are overwhelmed with the number of people who wanted to help in any way they possibly could."
