A four-year-old girl who went missing from an Australian outback campsite more than two weeks ago has been found safe.
Cleo Smith was returned to her parents after being rescued by police from a locked house, authorities said on Wednesday.
Police broke into a house in Carnarvon, a town about 100 km (62 miles) south of the campsite, early on Wednesday morning and found Cleo in one of the rooms.
A 36-year-old man has been taken into custody in relation to the disappearance, he said.
Police said the abduction appears to have been opportunistic and they expect to file charges later in the day.
Here's all we know about the case:
Where was Cleo last seen?
Cleo was last seen in her family's tent at about 1.30 a.m. local time (17.30 GMT) on October 16 at the remote Blowholes Shacks campsite in Macleod, about 900 km (560 miles) north of Perth, the capital of Western Australia state.
When her parents woke up the next morning, she was gone.
Australian police had feared Cleo had been abducted and offered a A$1 million reward for any information leading to her whereabouts.
The search
A team of 140 people had been working on the case with police fielding more than 1,000 tips from the public.
Cleo’s mum Ellie had discovered that the toddler was missing from the tent around 6am and that was when the search got underway on October 16.
The conditions with remote terrain meant it was difficult to search the area with some people using quad bikes and even a drone.
More than 100 people at the site were interviewed, and police carried out extensive searches by land and air.
"Police arrived at 7.10am and by 7.26am set up a protected site," revealed Det Superintendent Rob Wilde.
By 11am homicide detectives were at the scene and police were searching cars at the campsite.
Det Supt Wilde said that police had previously responded to around 200 possible sightings of Cleo around the country but none turned out to be her.
Officers were seen trawling through bins in the area in the hope of finding discarded clues in the days after she vanished.
The moment she was found
Eighteen days after the little girl vanished, police broke into a locked house in Carnarvon at about 1am on November 3 and found a little girl who told officers, "my name is Cleo".
Det sgt Cameron Blaine was one of four police officers who raided the house in Carnarvon.
He said: "There could have been anyone of the team but it turned out that I was one of four guys that was 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. Originally, to see her sitting there in the way that she was, it was incredible."
"One of the guys jumped in front of me and picked her up and I just wanted to be absolutely sure, it certainly looked like Cleo, I wanted to be sure it was her," he said.
"I said ‘what is your name?’ She didn’t answer, I asked again and she didn’t answer. I asked a third time 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."
How is Cleo doing now?
WA Commissioner Chris Dawson said: "What a great day. We now have returned Cleo to her loving parents. It's a wonderful day for this little girl and her loving family."
"She is physically OK. That was evident from the start," said state police homicide squad Senior Sergeant Cameron Blaine, who was one of four people to rescue the child.
"Taking her to the hospital we got assurance of that from people that know what they are doing."
He said finding her was "without a doubt" the best moment of his career.
"She is a very sweet, energetic girl, very trusting and very open with us," he said.
Family reaction
Following the good news that Cleo had been found safely her mum Ellie Smith took to social media to share her relief.
"Our family is whole again” she wrote on her Instagram page, next to a single heart emoji.
A close family friend also revealed an emotional message that Ellie wrote to her loved ones letting them know her 'beautiful girl is home'.
"To be woken at 4.50am with my phone going crazy at 4.50am and see the words Cleo is home alive and safe," she said on Facebook.
"Seeing Ellie saying her "beautiful girl is home" is nothing short of a miracle. We are so happy for her to be home."
What have police said?
Announcing the discovery earlier deputy commissioner Col Blanch said: “It’s my privilege to announce that in the early hours of this morning, the Western Australia police force rescued Cleo Smith. Cleo is alive and well."
The deputy commissioner added: “This is the outcome we all hoped and prayed for."
He said that "incredible police work" had led to Cleo's rescue and that the force would have "more to say" in the coming days.
Prime Minister Scott Morrison also welcomed the "wonderful, relieving news".
"Cleo Smith has been found and is home safe and sound. Our prayers answered," Morrison said on Twitter.
