Things came to a head when the Plebeian tribunes who supported Octavius vetoed the law in the Tribal Assembly. Cinna and his supporters began using violence to intimidate the tribunes to withdraw their veto, leading to a full-scale riot in the Roman Forum. Octavius quickly gathered an armed group of supporters and attacked Cinna, who was forced to flee the city. During the fight, Octavius’ men openly murdered a large number of newly enfranchised citizens, with Octavius using his authority as consul to justify the murders.
