An online classified sales advertisement offering a baby for 5,000 euros (5,500 dollars) in Germany has prompted police to open an investigation into possible human trafficking.
A 40-day-old girl has been taken from her family and placed in state care, police in the western city of Duisburg said in a statement on Thursday, adding that they are certain she is the child in question.
Employees at Ebay Kleinanzeigen, a popular online platform in Germany for buying and selling household items, contacted the police after the ad was posted late Tuesday with a picture of the infant, a spokesman for the website said.
Police said the family that posted the ad were refugees, without giving details on their nationality.
The parents were detained following a raid at their flat late Wednesday. However, they were later released after investigators found that other family members had also used the internet connection at the property.
An investigation is ongoing.
