The tragedy occurred on avenue du Président-Roosevelt, in Meaux, near the windshield replacement business.
It was Monday, around 12:45 p.m.
A mother and her very young daughter, sitting in her stroller, were crossing the dual carriageway, on the pedestrian crossing, when a large car appeared.
A 4 x 4 Range Rover, more precisely, whose driver seems not to have noticed their presence.
In shock, the little girl - aged 17 months - was seriously injured.
It was even in a state of absolute emergency that the child was transported - by the Smur, under police escort for greater speed - to the Necker hospital, in Paris 15th.
This Tuesday evening, the young victim is still alive.
As for his mother, in a state of shock, she was transported to the Meaux site of the Grand Hospital in eastern Paris (Ghef).
An investigation is opened for unintentional injuries
The driver of the car, who - according to the very first tests - was not under the influence of alcohol or drugs, remained at the scene after the accident.
This Meldois, aged 51, was taken into custody at the Meaux police station.
This man, completely unknown to the justice system, admitted the facts.
He was on the phone, using a hands-free kit, and would not have seen the mother crossing the road behind her stroller.
The Meaux public prosecutor's office has opened an investigation into unintentional injuries: a qualification which can still evolve depending on the state of health of the child.
As for the motorist, he was released and will be summoned to court at a later date.
