Late night revellers witnessed a large scale brawl in the early hours of Sunday morning as the CBD erupted with violence.
One witness said the fight appeared to start between security at one of the nightclubs and revellers on Mair street at 4.35am.
A crowd of up to 100 people watched on as about 10 males fought security and each other on Mair Street, the witness told The Courier.
The fight then continued on the footpath around into Lydiard Street.
Police arrived soon after at around 4.43 am and the crowd dispersed. It is unknown if any arrests were made at the scene.
The incident comes after the release of statistics last week showing crime in the city’s major streets had plunged over the past five years as police continue to deploy more resources into the busy area.
Crime statistics data collected between April 2011 and March 2016 from 15 major streets shows the number of recorded incidences showed a 23 per cent overall decrease between these dates.
While Mair and Lydiard Streets remain the standout hotspots for offences, the enforcement of the liquor accord, the use of CCTV , improved lighting and taxi ranks have all been attributed to the major drop off in CBD crime.
Public and security offences had seen the biggest drop, plummeting from a 2011-12 high of 136 down to 54.
Ballarat police have been contacted for comment.
