In a developing story, opening night at the fair turned violent when witnesses claimed a mob of Black teens beat white fairgoers in the streets, according to reports from a local Milwaukee news station.

Writes TMJ4:

Witnesses tell Newsradio 620 WTMJ and Today's TMJ4 of a mob of young people attacking innocent fairgoers at the end of the opening night of State Fair, with some callers claiming a racially charged scene.

Milwaukee Police confirmed there were assaults outside the fair.

Witnesses' accounts claim everything from dozens to hundreds of young Black people beating white people as they left State Fair Thursday night.

Authorities have not given official estimates of the number of people involved in the attacks.

"It was 100 percent racial," claimed Eric, an Iraq war veteran from St. Francis who says young people beat on his car.

Police video shows officers handcuffing at least one person, but police aren’t saying how many people they took into custody. 

It’s still unknown how many people were injured, because police are still fielding complaints from people caught in the melee, the news station reports.

As of early Friday morning, Milwaukee Police said they had no one in custody.
