According to police reports, the conspirators had been actively recruiting individuals, including minors, to execute attacks that would target children, teenagers, and members of the L.G.B.T.Q. community. The leader of the group was apprehended in Rio Grande do Sul on weapon possession charges, while a teenager was arrested for allegations related to child pornography. However, it is still unclear if any formal charges have been lodged against either suspect.

Lady Gaga's representatives, known for their commitment to L.G.B.T.Q. rights, have yet to respond to inquiries following the incident. This concert was part of Rio de Janeiro's initiative to boost tourism by hosting significant free events, similar to a previous performance by Madonna last year.
