Story highlights The teacher is being interviewed again to determine why he fabricated the story

He is hospitalized with non-life-threatening wounds

Paris (CNN) Police and security forces swarmed a Paris suburb Monday after a teacher claimed to have been attacked and stabbed by a masked man shouting support for ISIS.

But in an interview later at the hospital, the man admitted to making up the story, the Paris prosecutor told CNN.

Earlier, the male teacher told authorities that a masked man had stabbed him in the throat and abdomen while shouting that the attack "was for Daesh," according to the French newspaper Le Parisien.

The teacher is hospitalized with non-life-threatening injuries, officials said. It's not clear how he was injured.
