A 19-year-old student who threw an egg at French President Emmanuel Macron has been admitted to a psychiatric hospital after a medical examination.

The viral clip showed the egg bounce on Macron’s shoulder while meeting a crowd before the camera panned to officials detaining a man in the crowd.

The man was taken into custody, and an investigation was opened for “an assault on a person in a position of public authority,” Lyon prosecutors said. He didn’t know the police before.

The prosecutor’s office said in a statement Tuesday that the student was subjected to a mental assessment, which determined “lack of sensibility and the need for hospitalization.”

Macron was slapped in the face during a similar mob event in June. Like other French presidents, he enjoys spending time with the public, especially as part of the campaign for the French presidential election in April. Macron has not yet announced his candidacy but is expected to do
so.

The motivation behind the incident remains unclear.

An Elysée Palace spokesperson, who was with Macron at the time, told CNN the incident was being overblown.

“The President walked around for two hours, he was warmly welcomed and everything was calm. There is nothing to say about it because it did not disrupt his walking around,” the spokesperson said, adding: “I was next to the President, I can tell you there is no story.”
