track down#2
フランスのある教師が自身のカッターナイフによる傷の原因について，不謹慎な嘘をつきました。報道によると，傷は自傷によるものであるにもかかわらず，ISによる攻撃を受けたと叫んだようです。この発言により，いるはずもない犯人の追跡活動が行われました。教師は教育歴20年のベテランでした。
記事の中で気になった表現は"track down"です。ODによると"Find someone or something after a thorough or difficult search"と定義されております。同じくODで"track"を引くと，動詞には"Follow the trail or movements of (someone or something), typically in order to find them or note their course"とされており，"down"が付くことで徹底的に探索することを表しているようです。（Ume）
French teacher invented Aubervilliers school attack
The incident sparked a manhunt in the northern suburb, as police tried to track down the alleged attacker.
The anti-terrorism branch of the Paris prosecutor's office also opened an investigation for attempted murder in relation to a terrorist act.
Earlier on Monday, Education Minister Najat Vallaud-Belkacem visited the scene and vowed to increase security at French schools.
All classes at the Jean-Perrin preschool were cancelled.
Mayor of Aubervilliers Pascal Beaudet said it was not yet known what had motivated the teacher to lie.
He said the teacher had 20 years' experience and was "appreciated" by parents at the school.
