New video has emerged of an alleged brawl in Sydney's CBD on Saturday, which left a woman unconscious and four men in hospital.

Police said two groups of men were involved in a scuffle on Lime Street, at the King Street Wharf dining precinct, at about 10.30pm.

This new video follows the release of footage from a taxi dashcam at the weekend.

Four injured 29-year-old men and an unconscious 27-year-old woman were treated at the scene and then taken to St Vincent’s Hospital in Darlinghurst.

One of the men suffered a dislocated knee, while another had his nose broken in the fracas.

Four men were arrested nearby a short time later.

Three of the men, aged 18, 22 and 23, have since been charged with affray.

Another 23-year-old man has been charged with affray and malicious damage.

Business owners along Lime Street have told 9NEWS that violent scenes are uncommon along the popular restaurant strip.
