A group of children in Zurich were on a treasure hunt as part of a birthday party for 8-year-old Malia. They had to follow clues and unearth small presents.
But they found real treasure.
Malia says they discovered a jewellery box and when they opened it, there were lots of beautiful things inside, she explained.
The box was not part of the hunt and the adults took it to the police.
It had been taken from a nearby house during a burglary two weeks ago. Zurich police say it has now been returned to the owner – who has promised the children a reward for their find.
