Police in Brazil foiled a bomb plot at a packed Lady Gaga in Rio de Janeiro last night.
Police say they uncovered a planned attack involving improvised explosives by a group promoting the radicalisation of teenagers, violence and self-harm.
A man was arrested for possession of an illegal fire arm and a teenager was arrested for storing child pornography.
The concert broke records as Lady Gaga's biggest ever crowd with an estimated 2.1 million people gathering on Copacabana Beach to watch her perform.
The spectacle was free to attend and was organised by the city in a bid to boost the economy. It's estimate over half a million of the fans present had travelled from abroad. was
Similar concerts - like the one staged by Madonna in same venue last year - are scheduled to take place every year in May at least until 2028.
