Four more men from Western Australia have been charged over a "brutal and vicious" mass brawl in Chapel Street, which left a young man seriously injured.

A 19-year-old and three 18-year-olds were charged with affray, rioting, and assault-related offences on Monday.

Another 18-year-old boy was arrested and released without charge.

The group is accused of being in a fight involving about 20 people on Chapel Street, Prahan, about 1am last Thursday.
