The sister of a missing Ayrshire child has marked the 46th anniversary of his disappearance.
Sandy Davidson vanished from his grandparents' garden in Bourtreehill on April 23, 1976, when he was just three years old.
The tot – who is one of the country's oldest missing persons cases – had been playing with little sister Donna when he is believed to have chased a family pet dog out of the garden gate.
