Federal hate crime charges have been filed against a man accused of plowing a car into a crowd of people protesting against a white nationalist rally in Charlottesville, Virginia, last year, killing a woman and injuring dozens more.

The Department of Justice announced on Wednesday that a federal grand jury agreed to indict 21-year-old James Alex Fields, of Ohio, with 30 crimes, including one count of a hate crime resulting in the death of Heather Heyer, and 28 other hate crimes involving an attempt to kill other people, who were injured.

Fields already faces state charges of first-degree murder and other crimes.

Fields was photographed hours before the attack with a shield bearing the emblem of one of the hate groups taking part in the “Unite the Right” rally. The event last August began with white nationalists marching through the small university town, holding torches, chanting supremacist slogans and giving Nazi-style salutes.

A march on a local park the following day, which contains a Confederate statue, quickly descended into shocking levels of violence as the far right, many wearing armor and carrying clubs and sticks, clashed with those protesting against the event. The volatility escalated when Donald Trump weighed in to blame both sides for the clashes. Fields is accused of deliberately driving a car into a large crowd of anti-nationalist protesters in a narrow street, who were walking away from the main event. He has been in custody since then.

The attorney general, Jeff Sessions, issued a statement on Wednesday, saying: “We remain resolute that hateful ideologies will not have the last word and that their adherents will not get away with violent crimes against those they target. Last summer’s violence in Charlottesville cut short a promising young life and shocked the nation. Today’s indictment should send a clear message to every would-be criminal in America that we aggressively prosecute violent crimes of hate that threaten the core principles of our nation.”
