Police said the three girls - aged three, seven and eight - and a four-year-old boy had been returned to their home about 9.20am on Friday.

Inspector Regan Draheim said their mother was grateful the children were back home.

“She’s very relieved, obviously, as any parent would be with their children being returned,” Draheim said.

“She’s as relieved as anyone would be given the situation.”

Police allege Joshua Carter, with identifiable Batman ‘Joker’ themed facial tattoos, was seen taking the children from a Maraju Yakapari Road address in a white 2005 Nissan Patrol 4WD with the Queensland Registration 063BC9.
