By 9:18am VST, a calm had returned to the National Assembly as the lawmakers retreated into the Palacio Federal Legislativo. Speaker of the National Assembly, Julio Borges, spoke a half hour later calling for the Venezuelan armed forces to protect the will of the Venezuelan people and not that of a political party. Government supporters began to congregate at the entrances of the Palacio Federal Legislativo at about 10:40am VST and at 11:45am VST, National Guardsmen stationed at the legislative palace allowed the crowds to enter the National Assembly facility. Hundreds of people belonging to colectivos and pro-government groups then stormed the National Assembly armed with pipes, firearms and fireworks, proceeding to fire guns and tear gas throughout the area. By 1:30pm VST, colectivos were inside of the legislative palace assaulting individuals without any intervention from the National Guard. Some legislators made futile attempts to defend themselves from the government groups with fire extinguishers, Opposition lawmakers were beaten with objects and while some were attacked while lying defenseless on the ground. After hours of brawling occurred and many opposition officials were beaten, the National Guard finally withdrew pro-government groups from the facility. Following the attack, the walls and floors of the Palacio Federal Legislativo were left stained with the blood of opposition lawmakers. However, government supporters remained outside of the Palacio Federal Legislativo for hours, assaulting legislators as they left with the National Guard showing indifference to the pro-government attacks. By 7:10pm, authorities began to escort lawmakers to their vehicles and within twenty minutes, 90% of legislators were evacuated from the area, though journalists and photographers had to escape by their own will under a hail of bottles, fireworks and stones. As a result of the attack, at least 12 opposition officials and their staff were reported to be injured.
Following the attack, individuals injured could not receive treatment due to the shortage of medical supplies in the country and because the Bolivarian government prohibited the National Assembly from having proper medical insurance. Many asked for donations of gauze, bandages, antibiotics, antiseptics, IV solutions and painkillers.
