Today detectives searching for missing April Jones have been searching more than 20 sites, including a farmhouse where Mark Bridger is believed to have lived recently.
Officers have been at the house called 'Mount Pleasant' in the village of Ceinws, five miles from April's home town of Machynlleth.
Police officers were seen digging up paving stones and drilling off doors at the farmhouse, as part of their searches.
ITV News Special Correspondent Geraint Vincent reports on the search for April:
Earlier, Dyfed Powys Police were granted until 5pm tomorrow to continue questioning Mark Bridger, who has been arrested in connection with April's disappearance. The five year-old was last seen playing with her friends on Monday evening in Machynlleth. Her disappearance has prompted an "unprecedented" police operation to find her.
This evening police searching for the schoolgirl told the media at a news conference that "extensive" searches for the five-year-old have been taking place throughout the day and will continue "regardless" of the bad weather tonight.
ITV News' Rupert Evelyn reports on the police and rescue team effort to find April:
More than 400 people have registered their contact information and details of any specialist skills with police and officers have received more than 2,500 calls from members of the public.
Thanking all the volunteers, Mr John said: "All in all, we've had outstanding co-operation from members of the public, not just from this community. It quite takes you away really, it's quite a humbling experience."
The force is being supported nationally to answer all the calls with information.
"Following the appeals for information that we've made, we've received over 2,500 calls from the public," Mr John told reporters.
"All those need to be answered, and that is being done by all police forces throughout the country who have worked together to support the Child Alert line."
He said that the number of calls showed that the public want to assist police.
"I'm very heartened by it, it shows that the public care and want to help us."
