The statement added: “Her team worked closely with law enforcement throughout the planning and execution of the concert and all parties were confident in the safety measures in place.”

Security was tight at Saturday’s concert, with 5,200 military and police officers deployed to the beach where fans were reveling in the pop singer’s classic hits like “Born This Way,” which became something of an LGBTQ anthem after its 2011 release.

Homes in several states raided

Authorities arrested two people in connection with the alleged plot — a man described as the group’s leader in the southern state of Rio Grande do Sul on illegal weapons possession charges, and a teenager in Rio on child pornography charges. Police did not elaborate on their exact roles in the plot or on how the group came to target Lady Gaga’s free concert.

“Those involved were recruiting participants, including teenagers, to carry out integrated attacks using improvised explosives and Molotov cocktails,” police said.

The Justice Ministry said that it determined the group posed a “risk to public order.” It said the group falsely presented themselves online as “Little Monsters” — Lady Gaga’s nickname for her fans — in order to lure teeangers into “networks with violent and self-destructive content.”

During a series of raids on the homes of 15 suspects across several Brazilian states, authorities confiscated phones and other electronic devices. Although police said they believed homemade bombs were intended for use in the planned attack, there was no mention of the raids turning up any weapons or explosive material.

Cury said one of the suspects whose home was raided in the city of Macaé, near Rio, “had a religious motivation” and “claimed the singer (Lady Gaga) was a Satanist.”
