Slough Borough Council is caring for 10 children rescued by police in raids across the area yesterday morning.
Officers arrested 25 people for a range of offences after searching 17 addresses in Slough.
Commander Steve Allen said: “With promises of a financial return, some poor families surrender their children who are subsequently forced to commit crime. The operation is about us targeting those behind organised crime networks and the criminal exploitation of children.”
Chief executive of Slough Borough Council Ruth Bagley said: “Our main focus in this operation is to on the welfare of the children who are being exploited. We will ensure that any children who are presented to the council receive care, and efforts will be made to reunite them with their families.”
Agencies are working with authorities in other countries including Romania.
