How phone data and a 'needle in a haystack' piece of evidence led police to Cleo Smith - and the unanswered questions detectives are not shedding any light on
- Cleo was found just two minutes from police HQ and two miles from her home
- Officers said a tip-off, a car and phone data helped them locate the missing girl
- An unnamed 36-year-old man has been arrested and is expected to be charged
Australian police tracked down missing Cleo Smith thanks to a tip-off and forensic clues after finding her just two miles from her family home where she was hidden right under the noses of investigators.
The four-year-old, dubbed Australia's Madeleine McCann, had vanished from a campsite on October 16 and was found alone inside the bedroom of a rundown and locked Canarvon home by relieved detectives at 1am last night, 18 days after her disappearance.
The house was just two minutes from police headquarters and a 45-mile drive from the Blowholes campsite where she was staying with her family when she vanished, meaning the young girl could have been stashed away before the search operation was launched.
Police said a 'needle in the haystack' clue late on Tuesday night led to Cleo's discovery and a 36-year-old man who has not been named and charged was taken into custody.
While the force has not yet revealed the exact details that led to Cleo's discovery, they said phone data and a car in the area played a crucial role.
Officers have also remained tight-lipped about the suspect, why he was not in the house in the time and the circumstances in which Cleo was found.

Cleo Smith was reported missing from Blowholes Campsite on the west coast of Australia at 6.23am on October 16 by mother Ellie who said she awoke to find her daughter gone. Police found the girl 18 days later inside the bedroom of a locked home in Carnarvon, 47 miles from the campsite and two miles from her parents' house

Cleo disappeared from her family's tent between 1.30am and 6.30am as her mother Ellie Smith, step father Jake Gliddon and baby sister Isla were sleeping nearby. The tent zipper was undone, and the sleeping bag that Cleo was using had also disappeared.
Western Australia Deputy Police Commissioner Col Blanch said the mammoth search involved a task force of 100 officers and 'thousands of pieces of evidence'.
Helicopters, drones, dogs and officers were deployed in the countryside and nearby coastline in case she had wandered off but police soon pivoted to the theory that she had been taken.
Officers had previously spoken of trying to trace a car seen leaving the Blowholes campsite around 3am the day Cleo vanished.
Officers trawled through hours of CCTV footage, combed satellite images, interviewed other campers and even dug through rubbish heaps for any sign of the missing girl before a 'tip off' led them to the Carnarvon house.
The man arrested by police in the early hours was later pictured being taken to hospital with a bandage around his head after apparently being beaten by other inmates when taken into custody.

Neighbours described his as 'a loner' who had been behaving 'weirdly' in recent days, including one who recalled seeing him buying nappies in a nearby supermarket despite not having children.
Detectives say the man was not at the house when Cleo was found, but was arrested a 'short' distance away.
He is not known to Cleo's family and is not a registered sex offender, detective Ron Wilde added, but said he is 'known to police' for other issues, without elaborating. 'I have to be very careful about that,' he said.
'[Officers] have collected thousands of pieces of evidence, intelligence, data, witness statements,' he told Sunrise on Wednesday morning.
'That has a been a hard, hard slog.

'Everything contributed. Certainly phone data helped us.
'It will become apparent that when we put the puzzle together it all led us to one place.'
Police Commissioner Chris Dawson said a tip-off led officers to the Carnarvon house and 'a lot of forensic leads' had pointed in the same direction.
'There was some information we followed up on,' he told ABC Radio.
'We had been following a lot of the forensic leads and it led us to a particular house.
'We mounted our general duties police who did a tremendous job within minutes of arriving [at the house]... declared it a forensic scene and sealed it off which was just really, really good policing.'

Hours before Cleo was found, Wilde said he believed her disappearance was an 'opportunistic' kidnapping by someone who had only been aware of Cleo for a 'short time'. Police have not yet elaborated on whether any of that information turned out to be accurate.
The early-hours raid came after officers received a tip-off Tuesday night with 'really important information about a car', which they confirmed with phone data and 'a lot of forensic leads'.
Blanch said Tuesday night's tip was the final piece of the puzzle that allowed detectives to finally track down Cleo.
'We've collected phone data, witness statements, DNA, fingerprints, rubbish along the highways, CCTV - we've collected everything,' he said.
'The million dollar reward helped us with collecting even more from the members of the public. Everyone came forward to helping us.
'There were car movements, there were phone movements, there were antecedents of people, the jigsaw fit the puzzle. We had to find that needle. Last night the needle in the haystack came out and they acted in a heartbeat.'
Neighbours interviewed after the raid also recalled other signs that a child was being kept at the property, but said they only realised the connection to Cleo in hindsight.
Sahntayah McKenzie recalled hearing a little girl crying one night, but did not think anything of it at the time.
'Not last night, the night before it... I heard a little girl crying but I wouldn't expect it to be Cleo,' she told the West Australian. 'I didn't expect it would happen in this little neighbourhood, a lot of people know each other.'
It's reported that police were tipped off to the address after neighbours spotted the suspect buying nappies.
One of them told Seven News she became suspicious after seeing the suspect buying Kimbies nappies from a supermarket.
'The other day, I think it was Monday, we saw him in Woolworths buying nappies but we didn't click on who it was or what he was buying them for,' she said. 'Until now.'

Cleo had been sleeping in a tent alongside mother Ellie at a campsite the family often visited on the Western Australia coast when she vanished along with her sleeping bag some time in the early hours of October 16

Police said Cleo (pictured with mum Ellie and stepfather Jake) shouted 'mummy!' while being reunited with her parents, and that all three of them shared hugs and kisses
Another neighbour told Nine he had spotted the arrested man behaving bizarrely in recent days, driving at speed through the streets with his dogs in the front seat of his car.
'He's been acting a bit strange lately,' Henry Dodd told Nine News. 'He will get in his car, drive that fast.
'He doesn't have his dogs at the front [normally], he has his dogs out the back, but through this week he had his dogs out the front and he has been acting weird.'
Henry Dodd said police spent several hours driving up and down the street before breaking into the home.
Neighbours described the man as 'quiet' and said they wouldn't expect him to be involved.

When Cleo smiles and nods, he tells her: 'We're going to take you to see your mummy and daddy, OK?'

Cleo's mum Ellie Smith broke her silence on Wednesday morning, sharing a series of love heart emojis on Instagram after her daughter was found alive and well

This is the moment that four-year-old Cleo Smith was found alive by detectives inside a locked house in the town of Canarvon, Western Australia, 18 days after going missing while on a family camping trip
She is now safe and recovering in the company of her parents - having been pictured smiling from a hospital bed while eating an ice lolly, waving to the camera as her mother's hand rests on her leg.
Wilde said Cleo is 'physically OK' after being checked by doctors.
Mother Ellie then took to social media to express her relief, posting a picture of her daughter with the caption underneath: 'Our family is whole again.'
Speaking about the moment Cleo was found, Blaine said: 'It was a shock to start with, quickly followed by elation. That could have been any one of the team, but it turned out I was one of four guys that were fortunate enough to go through that door and make that rescue.
'We had always hoped for that outcome, but were not prepared for it. It was absolutely fantastic to see her sitting there in the way that she was. It was incredible.'
'I wanted to be sure it was her. I said, 'What is your name?' She didn't answer, I asked three times, and then she looked at me and said, 'My name is Cleo.'
'And that was it. Then we turned around and walked out of the house. Not long after that we got into the car and the officer called Cleo's parents. It was a wonderful feeling to make that call.'
Police used battering rams and crowbars to break their way into the Carnarvon house, located on the outskirts of town in a suburb called Brockman, with neighbours telling Daily Mail Australia they were first alerted to the commotion when flood lights lit up their cul-de-sac in the middle of Tuesday night.
'My nephews went up to see what was going on and then they saw cops leading out the little white girl,' a neighbour said.
He added that he has known the owner of the property for more than a decade, describing him as 'a loner' who 'kept to himself' and was not the type to stop and talk to others who lived on the street.
He last saw the man just three days after Cleo disappeared. 'His grandmother raised him... but after she died a year or so ago, nobody went over to [speak] to him,' the man said.
'He got a new car after… he used to park it in the driveway and then close the gate, every day, always went and put the car in the same spot and closed the gate.'
Former friends added that the man had not long been released from jail, though did not say what he was in prison for. Police said only that he was 'known' to them and was not a registered sex offender.
