THE three siblings who went missing from Adelaide’s southern suburbs have been found safe and well.

Police said a man has been detained for breaching his bail.

Police launched a search for the children, Ethan Lawson, 12, Jayden Lawson, 10, and Sienna Dodd, 6, on Thursday.

They had last been seen running away from football training at Bice Oval, Christies Beach, at 6pm on Wednesday.

Police on Friday said the children were believed to be with their father Dylan Lawson, 36, and possibly their mother, Chantelle Lawson.

South Coast officer-in-charge Superintendent Ian Parrott confirmed late Friday afternoon the children were now in the custody of “appropriate authorities” and he thanked the public for their support in relation to this matter.

“A man has been detained by police at this time for breaching his bail, but importantly the children are safe and well,” he said.

The children were described as being in “a family group” having left “alternative care”. Both parents were known to police.

An Education and Child Development Department spokesman refused to confirm whether the family was known to Families SA.

“SAPOL has released the pertinent information in relation to this matter and we are not in a position to add to that while the investigation is live,” the spokesman said.

Police this morning focused search efforts on family and friends of the children.

They spent 45 minutes on Friday morning at the father’s Hackham West home.

They arrived at 9.30am and searched his house, car and bins before leaving at 10.15am.

Neighbours told The Advertiser they had not seen the children at the property for about month and the father for about two and a half weeks.

One neighbour said he often saw the children, who he described as “lovely”, playing in the street but that the father kept to himself.

Another neighbour said she was shocked to discover the children were missing and hoped they could be found safe and well.

Paul Daly of Christies Beach Football Club said a carer at the club saw the trio run from the oval and at that point called police to report it.

Police on Thursday issued a public appeal for information on the missing siblings and released photos of them — 21 hours after their disappearance.

Friends of the siblings at the football club said they were shocked by the trio’s disappearance.
