A worried Facebook friend of the couple in Aisne in northern France alerted police after the child’s father posted a photo of his one-month-old baby with injuries on its body, Le Parisien reported.
It prompted a police investigation that led to both parents being charged on Wednesday night with violence on a minor.
According to a source close to the investigation cited by the newspaper, police were alerted on Monday by a friend of the couple who said they had seen a photo of the baby on the social networking site in which it appeared to be “abnormal”.
After carrying out checks police confirmed that the baby was indeed “in a bad state” and the mother was summoned to the police station with her child, who, according to the source, was in an even worse state than in the photo.
The father was questioned later that day. During the questioning, he explained that he had hit the child in the evening because he couldn’t stand the baby’s cries and had shared the photo on Facebook “for fun”.
The mother, meanwhile, claimed that she had not alerted police because she was worried that her husband would leave her.
Prosecutors have requested that the unemployed couple, who are in their twenties, be remanded in custody.
Although the baby is thought to have neurological problems as a result of the abuse, the extent and severity of the abuse is not yet known.
