Emotional moment Allison Langdon learns missing four-year-old Cleo Smith has been found alive

Today host Allison Langdon breathed a sigh of relief as she reported that missing four-year-old Cleo Smith had been found alive and well on Wednesday.

Cleo was found 18 days after vanishing from her family’s tent in a remote campsite in Western Australia, in a disappearance that made headlines around the world.

‘This is huge news. She’s been missing for about three weeks now,’ a stunned Langdon told viewers as WA Police confirmed the discovery at 7:20am.

Her co-host Karl Stefanovic continued: ‘It’s breathtaking news. After what has been a tortuous couple of weeks for her mum, stepdad and her father. The searches, the not knowing, all the speculation… we don’t know what happened to her.’

A relieved and emotional Langdon agreed, saying: ‘Oh my goodness, [I feel for her] mother Ellie who has been at that search site every single day.’

‘For her to be found alive and well, that is incredible news,’ the mother of two added, before placing a hand on her heart and saying: ‘They’ve got their little girl back.’

The story no doubt affected Langdon personally because she has a son Cleo’s age, named Mack, as well as a younger daughter, Scout.

Cleo was miraculously found alive on Wednesday, 18 days after vanishing from her family’s tent in a remote campsite in Western Australia.

Police broke their way into a locked house in Carnarvon, 75km from where she went missing, about 1am on Wednesday and found the girl in one of the rooms.

WA Police Deputy Commissioner Col Blanch confirmed just before 7am AEST that little Cleo is alive and well and had been reunited with her relieved parents.

‘One of the officers picked her up into his arms and asked her “what’s your name?”,’ he said.

‘She said: “My name is Cleo”.’

A man from Carnarvon was arrested at the home and has taken into custody to be questioned by detectives.

‘This is the outcome we all hoped and prayed for,’ Deputy Commissioner Blanch said.

‘It’s the outcome we’ve achieved because of some incredible police work. I want to thank Cleo’s parents, the Western Australian community and the many volunteers.’

‘And of course, I want to thank my colleagues in the Western Australia Police Force.’

Police will provide more details on the rescue of Cleo later on Wednesday.

‘For now – Welcome home Cleo,’ Deputy Commissioner Blanch concluded.
