A newborn baby was rescued from an underground rubbish container in the Mejorada del Campo area of Madrid on Wednesday morning.
A man walking his dog heard what he thought were the cries of a baby and alerted the police, who in turn called on the fire service to assist in accessing the underground container.
The baby was found in a plastic bag inside a rucksack but was said to be in good health.
An investigation has been launched to try to identify the parents.
