The incident happened earlier today
A teacher who claimed he was stabbed by a masked raider citing Islamic State has admitted making it all up, according to French prosecutors.
The 45-year-old sparked a manhunt on Monday after telling police an assailant burst into his classroom before lessons began at the kindergarten in Aubervilliers, northern Paris.
The teacher had claimed the raider attacked him with a box cutter and scissors found in the classroom and said: "This is Daesh (IS), it's a warning."
An official said: "He is being interviewed with a view to establishing the reasons for this invented story."
The teacher was taken to hospital after being stabbed in the side and throat. It is now unclear how he got his injuries, which were not life-threatening.
The French capital has been on a heightened state of alert in the wake of the recent atrocities claimed by IS.
A total of 130 people were killed in a series of coordinated attacks by gunmen and suicide bombers on the Stade de France, the Bataclan concert hall and restaurants in the French capital on 13 November.
The terror group, which control swathes of Syria and Iraq, had vowed to attack France which is a member of the US-led coalition carrying out airstrikes against it.
Jihadists have also made specific threats against teachers in France, with propaganda material claiming they were "enemies of Allah" and that schools cultivated "ignorance and moral corruption" in children.
The authorities said this threat had been taken into account and safety instructions had been issued to educational establishments, including bag checks.
Education Minister Najat Vallaud-Belkacem said the terrorist threat was "real and permanent (and) all public places deserve protection, particularly schools".
"We will continue to reinforce security measures at schools in a context where schools feel threatened," she said.
In March 2012, gunman Mohamed Merah killed three children and a teacher outside a Jewish school in an attack which also led to the deaths of three paratroopers.
