Brazilian Authorities Prevented a Terrorist Attack at Lady Gaga’s Megashow, Which Gathered Over 2 Million in Rio; Coordinated Action Involved Warrants in Several States
On May 3, 2025, Copacabana Beach in Rio de Janeiro was the stage for one of the biggest musical events in history: the free megashow by Lady Gaga, which brought together between 2.1 and 2.5 million people, making it the largest performance ever conducted by a female artist in the world. The event, part of the initiative Todo Mundo no Rio, aimed to promote tourism and the local economy through major international shows.
Despite the success and grandeur of the show, a terrorist plan almost turned the celebration into a tragedy. Thanks to the effective action of the security forces, the attack was thwarted, allowing the event to proceed without incidents.
Terrorist Threat: The Fake Monster Operation
Days before the show, the Civil Police of Rio de Janeiro, in collaboration with the Ministry of Justice and police forces from other states, initiated the Fake Monster Operation. The investigation revealed that an extremist group was planning to carry out attacks during the concert, using improvised explosives and Molotov cocktails.

The group spread hate speech, especially against children, teenagers, and the LGBTQIA+ community, recruiting young people via the internet to carry out the attacks. During the operation, 15 search and seizure warrants were executed in various states, resulting in the arrest of two suspects: an adult in Rio Grande do Sul for illegal possession of weapons, and a teenager in Rio de Janeiro, accused of possessing child pornography. Both were involved in organizing the attack and disseminating extremist content online.
The authorities chose to keep the operation confidential until the event took place to avoid panic among attendees. The concert occurred without incidents, and Lady Gaga was not informed about the threat until after the performance, as reported by Los40.
Cultural and Economic Impact of the Event
The Lady Gaga show not only broke audience records but also had a significant impact on the economy and tourism of Rio de Janeiro. Following the announcement of the event, there was a substantial increase in demand for flights and accommodations in the city, especially in the Copacabana area. Travel agencies reported growth in bookings, and platforms such as Airbnb reported an increase of up to 150 times in searches for accommodations in the city.
Additionally, the event was broadcast live by TV Globo, Globoplay, and Multishow, reaching a global audience and solidifying Rio as a prominent destination for major international events. This strategy reinforces the campaign proposal Todo Mundo no Rio to boost the economy through culture and entertainment.

Repercussions and Future Measures
The attempted attack rekindled debates on online radicalization and the spread of extremist rhetoric in Brazil. In response to revelations that the messaging app Discord was used to coordinate the plan, federal deputy Guilherme Boulos (PSOL-SP) submitted a representation to the Federal Public Ministry requesting the suspension of the platform in Brazil. He argued that the service has been repeatedly used by criminal groups to commit crimes such as terrorism and glorification of Nazism.
International media, such as BBC News, CNN Brazil, and The Washington Post, highlighted the actions of Brazilian authorities in preventing the attack, praising the swift response of the security forces.
Lady Gaga’s megashow in Copacabana will be remembered not only for the grandeur and emotion provided to the audience but also for the decisive action of the security forces in preventing an imminent tragedy. The event reinforces the importance of vigilance against extremist threats and confirms Brazil’s role as a reference in hosting major cultural events safely and responsibly.
