A SIX-year-old boy allegedly killed a premature newborn baby after dropping her on the floor.
A criminal investigation has been launched after the horror unfolded at the Jeanne-de-Flandre Children’s Hospital in Lille.

A baby identified as Zayneb-Cassandra was declared dead yesterday.
She suffered a traumatic brain injury last Friday after allegedly being dropped on the floor by the boy.
Despite being reported as a “disruptive presence” in the hospital, the boy was found alone with the unconscious baby in a neonatal unit.
He was spotted wandering around the hospital unattended.
Investigators said the boy “treated her like a doll”.
The baby was her mother’s first child, and she was delivered by cesarean section, said one investigating source.
Zayneb-Cassandra’s grandmother told the Voix du Nord newspaper: “The boy would arrive at 7am and spend all day running up and down the hallways.
“All the mothers were complaining, and a nurse even warned the child’s mother that there was a problem. He was entering the other rooms.
“He also entered Zayneb’s room for the first time. He said she looked like a doll, and my husband, who was there, took him out.”
Zayneb was found unresponsive on the floor, next to the six-year-old, who was on a chair.
“It seems he tried to grab her by her nappy, and she fell on her head,” said Zayneb’s grandmother.
The baby was rushed to intensive care – but was declared dead after suffering “a serious brain injury”.
An investigation has been opened by the juvenile unit of the Lille Judicial Police Service, in conjunction with local prosecutors.
A spokesman said: “Investigations are currently underway in this case.”
The hospital also announced the opening of “an internal administrative investigation”.
