Victoria Police has promised to investigate how it deals with ethnic groups after it settled a civil case over racial profiling of Afro-Australian men.

Police will hold an inquiry into their public relations and cultural awareness training as part of a settlement with six young men who claimed they were racially discriminated against in the Flemington and North Melbourne areas between 2005 and 2009.

The men, who were teenagers at the time, claimed they were assaulted by police and were often stopped, questioned and searched because they were black.

An announcement on what actions police will take in response to the inquiry is due by December 31 this year.
