A desperate search to find a little girl who vanished 24 hours ago from her family's tent has taken an alarming turn as police search vehicles leaving the campsite.
Cleo Smith, four, was last seen at about 1.30am on Saturday at the Blowholes campsite on the coast at Macleod, north of Carnarvon, in Western Australia.
When her family woke up[ about 6am, Cleo was nowhere to be seen.
Campers have been leaving the site as emergency services scour the area, which was not ordered by police but is preferred.
Inspector Jon Munday said officers have been stopping cars and caravans to search interiors and take drivers' details before vehicles leave the area.
A frantic search is underway after Cleo Smith disappeared from her family's tent during the early hours of Saturday morning. Pictured: Cleo in the outfit she was wearing when she went missing
'We are trying to paint the picture of who was around here during the window of opportunity between the early hours of Saturday morning and 6am Saturday and what leads that could give us,' he said.
As a major search operation nears the end of its second day, Mr Munday said detectives were no closer to finding the little girl or clues about her mysterious disappearance.
He said it was very unusual for a child to disappear from a tent they shared with their parents during the middle of the night, and confirmed her sleeping bag was also missing.
'Unfortunately we have not had any major breakthroughs,' he told reporters on Sunday.
'[The disappearance] is extremely concerning and not something we come across very often at all.
'We are throwing everything at this, but at this point in time we do not have any answers about where Cleo is.'
Police aren't ruling out the possibility she has been abducted, after urging every newsroom in Western Australia to broadcast details of the missing girl on Saturday.

'We are still in very early stages,' Inspector Munday said.
'Everything is on the table, and hopefully we will be ruling them [leads] out as we go.'
Cleo's heartbroken mother Ellie Smith issued a plea for help finding her young daughter.
'It's been over 24 hours since I last seen the sparkle in my little girl's eyes! Please help me find her',' she wrote in a Facebook post on Sunday.
'Last seen 1.30am and gone when woken up at 6am from our shared tent. Very very unusual for Cleo. Please if you see anything unusual or suspicious call the police'.
The young girl was wearing pink one-piece pyjamas with a blue and yellow pattern when she was last seen.
