Overview
- An image shared on social media showing a pistol, a knife and small canisters with the phrase “la retribución viene pronto” circulated among students, prompting panic and some class suspensions.
- UNAM activated security protocols and filed a formal complaint with the Mexico City prosecutor’s office (FGJCDMX).
- The city’s Secretariat of Citizen Security reinforced patrols outside the campus as its Cyber Police analyze the image and the account, coordinating with prosecutors to assess any real risk.
- Access controls were tightened and interior patrols and university brigades were deployed; officials later reported the campus was operating normally.
- The scare follows a return to in‑person classes under enhanced measures—facial‑ID turnstiles, panic buttons, better lighting and expanded mental‑health services—installed after a fatal stabbing on Sept. 22, 2025, for which Lex Ashton remains in preventive detention.
