In this report, Amnesty International researched the way in which arrests by police forces in Mexico occur, specifically, when the authorities alleged that they arrest a person in flagrante delicto; that is, at the time when a crime was being committed. We found that, in Mexico, the arrests of people who were allegedly committing a crime at the time of the arrest, do not serve as a genuine response to the crimes being committed in the country, but are used by the authorities illegally, mainly against those who face historical situations of discrimination, with a worrying impact on young men living in poverty.
