Following the mobilization day on October 1st, several regional administrators in France, known as prefects, wrote to the parents of minors who were detained during protests. This included the Pas-de-Calais, the Ain, and the Pyrénées-Orientales departments. In the northern department of France, about forty schools were affected by the movement involving several thousand high school students. Over the course of a day, 80 people were detained, with 48 detentions recorded, according to the prefect in a statement at the end of the day. François-Xavier Lauch, the prefect of the Pas-de-Calais, wrote to the parents of the minors who were detained and placed in custody, expressing "strong disapproval" of their children's behavior. He stated that the actions of the students could expose them to judicial and disciplinary sanctions, which could go as far as exclusion from school, and noted that these actions might involve the parents' responsibility. Lauch asked parents to ensure their children refrained from demonstrating in the coming days. Similarly, the prefect of the Pyrénées-Orientales, Pierre Regnault de la Mothe, wrote to the parents of detained students, urging them to ensure their children's behavior conformed to the laws and regulations. The prefect of the Ain, Louis-Xavier Thirode, also wrote to the parents of the minors who were detained and/or placed in custody using similar wording. He informed the school principal, the academy director, the mayor of the commune, and the public prosecutor of the acts committed by the students. Thirode requested that parents inform him of the measures they intended to take to ensure their children strictly respected the laws and regulations and followed the instructions given. High school students have been mobilized in the streets for a week to demand more resources for their education and schools. The strongest part of the movement took place on October 1st. According to figures from the Ministry of the Interior, nearly 2,000 people (1,949) were detained in one day.
