Brazilian police said they thwarted a bomb attack planned for Lady Gaga’s concert on Copacabana beach in Rio de Janeiro on Saturday.
The Civil Police of Rio de Janeiro state, in co-ordination with the justice ministry, said suspects had recruited participants to carry out attacks using improvised explosives and the plan was aimed at gaining notoriety on social media.
The person responsible for the plan and a teenager were arrested, the police said on X.
A crowd of more than two million people gathered for the concert, which was free to attend.
Police said the group that planned the attack had been spreading hate speech, mainly against children, adolescents and the LGBTQIA+ community.
The alleged mastermind was arrested for illegal possession of a firearm in the southern state of Rio Grande do Sul, while the teenager was detained for storing child pornography in Rio.
Those responsible were also promoting the radicalisation of teenagers, including self-harm and violent content “as a form of belonging and challenge among young people”.
The justice ministry said the suspects had identified themselves as Lady Gaga fans, known widely as “Little Monsters”.
Police issued search warrants across the states of Rio de Janeiro, Mato Grosso, Rio Grande do Sul and Sao Paulo, and electronic devices and other materials were seized.
“Operation Fake Monster” was launched following a tip-off from Rio state police intelligence, which uncovered online groups encouraging violence among teenagers using coded language and extremist symbolism.
The concert was paid for by the city in an attempt to revitalise Rio’s economy, with expectations it could bring in $100m (£75m).
In a massive security operation, 5,000 officers were deployed and attendees had to pass through metal detectors. Drones and facial recognition cameras were also used to police the event.
