MINNEAPOLIS (AP) _ A new federal lawsuit claims that for at least two years, dozens of Red Wing High School students mocked African-Americans during homecoming week by wearing low-slung pants, oversized sports jerseys and flashing gang signs.

The lawsuit filed in in federal court last week claims the activity created a racially hostile environment and administrators failed to stop it or punish the participants.

The day was unofficially known as Wednesday Wigger Day. The lawsuit says wigger is a pejorative word for a white person who imitates the mannerisms, language and clothes associated with black culture.

The lawsuit says the event left Quera Pruitt, one of the few black students at the school, with extreme emotional distress. She graduated in 2010. She is suing for more than $75,000.

The district denies the allegations.
