The events took place Wednesday evening at Guérande, Loire-Atlantique.
A man, under the influence of alcohol and drugs, stabbed his wife.
The latter, wounded in the hand, has managed to escape the shelter and find refuge in a trade located in place Saint-Aubin in the intra-muros.
She asked that called the cops because her baby of 3 months had stayed at his home.
When the military arrived on the scene, the husband threatened to throw the child out the window. And then, finally, the suspect has been challenged without resistance.
The woman and baby were taken to the emergency room. The baby has not experienced violence.
