Overview

• More than 20 UNAM faculties, CCHs and preparatory schools suspended in‑person classes or declared paros, with many shifting to virtual instruction starting Sept. 29.
• The Faculty of Chemistry led the move after emailed and social media threats, and multiple units soon followed, including Economics, Law, Psychology, Engineering and several CCH campuses.
• UNAM’s general counsel reported six formal complaints filed and more being prepared with the Cyber Police and Mexico City prosecutors, noting many threat messages were forwards or reposts.
• Federal authorities are coordinating with the university, as President Claudia Sheinbaum said the security cabinet is assisting and a mental‑health program will be presented soon.
• Security protocols and reviews are underway across campuses—messages have appeared via Facebook, email and bathroom notes, inspections like ENP 8 found no explosives, and CCH Sur began infrastructure checks for cameras, lighting and panic buttons.
