TOULOUSE, France (AFP) — A French hospital launched an urgent appeal Saturday for a man to return his kidnapped two-month-old son, warning that the little boy’s life was in grave danger.

Baby Tizio was undergoing emergency treatment for an undisclosed illness and being fed with gastric and intravenous tubes when he was snatched on Friday evening from a children’s hospital in the southern city of Toulouse, triggering an abduction alert.

The authorities say his life is at risk if he does not receive immediate medical care.

“I want to talk to Brendan, Tizio’s father, to remind him of the gravity of his son’s condition, that his life is in danger, and he needs to take his boy to the nearest emergency department urgently,” the CHU Purpan hospital’s director Anne Ferrer told reporters.

“The medical team is ready to welcome Tizio or to pick him up from wherever he is,” she added. The 33-year-old unemployed father was separated from Tizio’s mother but they appeared to have been on cordial terms and he visited the baby in hospital every day.

A source close to the case said Tizio’s kidnapping was “incomprehensible”.

In the alert issued on Saturday, the hospital said the baby was abducted at around 9:00 pm on Friday evening after spending the entire day with his father, although a source close to the probe said the exact time was uncertain.

Brendan was described as tall and slender with a full beard and long black-brown curly hair.

The “abduction alert” in France was inspired by the Amber Alert child abduction system set up in the United States in 1996 after the kidnap and murder of a nine-year-old girl in Texas.

The French system has been used more than 20 times since it was established in 2006, and all the children were found safe and sound, all but two of them very quickly.
