French teacher 'invented' story about Islamist attack - judicial source
"He is being interviewed with a view to establishing the reasons for this invented story," an official said.
Earlier on Monday, other French officials told how the teacher had reported that a hooded man claiming a link to the militant Islamist group had attacked him with a knife-like weapon as he prepared for classes in a school north of Paris.
