FARGO, N.D. — A Moorhead, Minnesota man has been charged in federal court in North Dakota in connection with a May demonstration that turned violent in downtown Fargo.

U.S. Attorney Drew Wrigley says Jonathan Montanez has been indicted on one count of civil unrest. Montanez is accused of damaging a Fargo police vehicle while agitating a crowd May 30.

What started out as a peaceful march through Fargo to protest the death of George Floyd in Minneapolis turned ugly when protesters damaged buildings and vehicles in the city’s downtown after a two-hour, face-to-face showdown with police.

Montanez was arrested by FBI agents Wednesday and has a detention hearing on Friday.

He is the second person to be indicted for the Fargo violence. Errick Toa of Fargo was the first to be charged with similar allegations in July.

Wrigley says the charge against Montanez took time because there was a large crowd from that day that included people in face coverings and that there was thousands of hours of video evidence for investigators to sift through, KFGO reported.

Wrigley said the federal government is still actively investigating the events of May 30.

Protests have taken place around the country following Floyd’s death in Minneapolis. Floyd, a Black man, died after a white officer pressed his knee into his neck for several minutes even after he pleaded for air and stopped moving.
