A 45-year-old Portuguese woman is in custody in France after a naked baby girl was found shivering in the boot of her car.
The Mail reports the woman had kept the little girl's birth a secret from her husband.
The baby was found lying in a basket suffering from dehydration after the woman left the vehicle at a garage in Brignac-la-Plaine.
Mechanics found the baby inside after investigating cries coming from the boot. Police officers and doctors raced to the scene and took the little girl into care.
The child is now to undergo DNA tests to find out her exact age, and if the woman is her biological mum.
Neighbours of the couple told reporters that that they were shocked by the news.
One local resident said: "They are people like any others and not dirty. I went to their house several times and there was never any trace of a baby."
The Sud Ouest newspaper said the couple's three other children attended a local school and 'appeared normal'. They claim the mum has told the police that her husband was unaware of the baby's existence and that she gave birth in a corridor of her home, assisted by a neighbour.
