Seventeen search teams are part of the operation to find missing five-year-old April Jones.
Earlier today, Insp Gareth Thomas from Dyfed Powys Police discussed the search with our reporter Kevin Ashford.
"It's an incredibly difficult searching environment" he says. "We've got steep mountain sides, dense forestry, and fast-flowing rivers, as well as mineshafts and quarries".
"In this inquiry, I've never seen anything quite like it. Everybody's motivation is incredible. I've been speaking to officers who've not wanted to go on leave, or take rest days, because they want to be involved in the search".
Prisoners in HMP Shewsbury have donated a bench in memory of missing five-year-old April Jones.
More than two hundred people took part in a charity walk to raise money for the April Jones Fund.
As the search for missing five year old April Jones continues, well-wishers light candles and lanterns for her.
