April Jones' mother has made a tearful plea for information that could lead to her five-year-old daughter who was reported missing on Monday evening.
In her first public appearance, Coral Jones said: "There must be someone out there who knows where she is and can help police find her.
"We are desperate for any news. April is only five years old. Please, please help find her."
Detectives were tonight given an extra 12 hours to question abduction suspect Mark Bridger about April's disappearance. The 46-year-old has been interviewed by detectives twice since his arrest on Tuesday afternoon.
Dyfed Powys Police also confirmed to ITV News today that the missing schoolgirl has cerebral palsy.
ITV News' Special Correspondent Geraint Vincent reports:
On Wednesday police investigating April's disappearance took the unusual step of releasing images of aMark Bridger and his car in an appeal for information.
The 46-year-old is being questioned on suspicion of abduction and has been in custody since Tuesday afternoon. His Land Rover Discovery vehicle was seized by police and samples have been sent for forensic testing.
Police want to speak to anyone who saw either Mr Bridger or his car between Monday evening and Tuesday afternoon to get in contact.
Earlier, police asked volunteers to stop searching for five-year-old April Jones who went missing from her home in Machynlleth, mid-Wales on Monday evening.
In a briefing this morning, Supt Ian John of Dyfed Powys Police said he was concerned for their safety because of the challenging terrain around the town and asked them to leave the search to the "trained and skilled people that we have".
Specialist officers including dog handlers and mountain rescue teams searched throughout the night. Police believe April is likely to be found "fairly close" to where she was last seen.
The search is focusing on dense woodland areas and the River Dyfi. Coastguard boats and a hovercraft have been brought in to help specialist teams search the estuary and river banks.

Police have stressed that a number of lines of investigation remain open in the case.
Supt Ian John said that forensic samples taken from Mr Bridger's vehicle have been fast-tracked and are likely to be a "key part of the investigation".
April's parents said in a statement on Tuesday night that their lives have been "shattered" by the five-year-old's disappearance and have pleaded for her safe return:
April Jones was last seen around 7pm on Monday evening. She had been playing with friends near some garages close to her home on the quiet Bryn-y-gog estate in Machynlleth, Powys.
Child witnesses say April was seen getting into the driver seat of a grey van-like vehicle, which then drove off.
Police are appealing for anyone with information to contact them by dialling 0300 2000 333.
