Washington • Prosecutors on Thursday filed additional charges against more than 200 protesters who were arrested during President Trump's inauguration in January.

While the majority of the protesters were initially charged with one count of felony rioting, a grand jury returned a superseding indictment and added new charges: inciting or urging to riot, conspiracy to riot and five counts of destruction of property.

The additional charges were based on evidence gathered during an ongoing investigation by prosecutors and D.C. police.

Prosecutors also charged three individuals - Dylan Petrohilos, Kyle Wright and Matthew Hessler - for the first time.

Petrohilos, a 28-year-old graphic designer, was charged with rioting, conspiracy and multiple counts of destruction of property.

In an interview with The Washington Post this month, Petrohilos said officers broke through the door of his Petworth home early April 3. Police were led to the house after an undercover police officer secretly attended protest-planning meetings in the weeks before the Jan. 20 inauguration, court documents show.

Prosecutors also dismissed charges against three defendants. They are Bradly Collins, Sagen Lancaster and James Sullivan.

Authorities have alleged that members of Disrupt J20 were behind inauguration protests that turned violent. Some activists, wearing masks and dressed in black, smashed downtown store windows and burned a limousine, resulting in more than $100,000 in damage, officials say. Six officers were injured, including one who was knocked unconscious when a brick or piece of metal thrown by a protester hit him in the head. Officials allege that the protesters employed "black bloc" tactics, most commonly linked to anarchists.

One defense attorney involved in the case argued that prosecutors are unfairly targeting the demonstrators.

"The superseding indictment is sheer government abuse of power," Jason Flores-Williams said. "They are prosecuting people not based on evidence, but for who they know and who they associate with. It's unconstitutional and repressive."

A hearing for some of the defendants is scheduled for Friday in D.C. Superior Court.

Prosecutors said one of the protesters threw a patio chair at a police officer, causing the officer to fall off his motorcycle.
