According to the BBC, a stolen helicopter reportedly flown by a police officer flew above the Venezuelan Supreme Court in Caracas and dropped 4 grenades along with a slew of bullets. The police officer responsible, Oscar Pérez, issued a statement on Instagram calling for Maduro to resign and for a resistance to "tyranny". The move was in response to the Supreme Court's support of Venezuelan president Nicolás Maduro, who is the target of ongoing nationwide anti-government protests
