Prosecutors in Spain are investigating 849 cases of newborn children stolen from their mothers and sold to other families for profit, the country's attorney general has said.
Candido Conde-Pumpido said that 162 cases had already been referred for trial and only 38 have been dropped for a lack of evidence.
He said "a great many Spaniards" had been affected by the alleged thefts, which took place "over a prolonged period of time".
It is well documented that babies were taken from women who had supported the defeated Republican side after Spain's 1936-39 civil war.
However, some of the baby trafficking cases are as recent as the mid-1990s.
Mr Conde-Pumpido's office was alerted to the cases by an association of people searching for lost children or parents.
