On 27 June 2017, there was an incident involving a police helicopter at the Supreme Tribunal of Justice (TSJ) and Interior Ministry in Caracas, Venezuela. Claiming to be a part of an anti-government coalition of military, police and civilians, the occupants of the helicopter allegedly launched several grenades and fired at the building, although no one was injured or killed.

Interior Ministry Communications and Information Minister Ernesto Villegas said the helicopter fired fifteen shots at the Interior Ministry as a reception for 80 people celebrating National Journalists' Day was taking place.
