Brazil tightens security for Carnival events after disruptions and thefts

Authorities in Brazil implemented heightened security measures during Carnival celebrations following several incidents. In Rio de Janeiro, the Acadêmicos de Niterói samba school kept its parade vehicles covered at their assembly point for security related to a parade about President Lula, who arrived at the Sambadrome under a heavy security detail without interacting with the public. Police in Rio also conducted an undercover sting operation, with officers wearing costumes, to catch phone thieves.

Separately, São Paulo's Guarulhos airport was closed for about three hours on Sunday due to unauthorized drones in the area, disrupting flights. In the city of São Paulo, officials announced changes to Carnival security, including using undercover agents and altering ambulance routes, following previous disturbances. The city's mayor, Ricardo Nunes, also recreated a municipal patrol unit within the city guard.
