Brazilian police said they had arrested two people in connection with a foiled plot to attack Lady Gaga's packed mega-concert in Rio de Janeiro. Rio's civil police force said that "together with the ministry of justice" it had "prevented a bomb attack that would have occurred at Lady Gaga's concert in Copacabana" on Saturday night (local time).

Unidentified suspects were “virtually recruiting participants to carry out attacks” to gain online notoriety, according to the Rio de Janeiro Civil Police.

A sea of people filled Rio de Janeiro’s Copacabana beach on Saturday as pop superstar Lady Gaga played a colossal free concert in the Brazilian city, with more than two million fans said to have attended.
