Grenades were dropped and shots were fired on Venezuela’s Supreme Court from a helicopter on Tuesday, allegedly stolen and piloted by a police officer who remains at large, according to authorities.

The dramatic scene was captured and disseminated widely on social media, showing a helicopter circling overhead in Caracas while shots and explosions are heard. No injuries or deaths have been reported as a result of the operation.

The police officer suspected to be behind the attack, Oscar Perez, released a statement on Instagram to denounce the government as criminal.

“We are a coalition of military employees, policemen and civilians who are looking for balance and are against this criminal government,” he said.
