The title of the article is "An attacker did not cut her hijab". It means there was an 'attacker' but he didn't cut her hijab. However, as per the police officer, the attack itself is 'did not happen' which means there is no the attack at all.
How does an attacker exist without an attack???? Your title is totally misleading readers. I don't know the writer's education background, but, obviously, he/she lacks some basic logical thinking skills and need to be trained properly, maybe by the 11-old-girl.
