July 10 (UPI) -- An eighth suspect has been arrested and charged in an alleged plot to attack last month's Ultimate Fighting Championship event held at the White House, federal prosecutors said.

The suspect was identified as 21-year-old Chandler Scaggs of Chapmanville, W.Va.

The Justice Department said in a statement that he and the other seven suspects were charged in an indictment returned Thursday in Columbus, Ohio, with two conspiracy counts: providing material support to terrorists and conspiring to murder government officials on government grounds. Jail records indicate that Scaggs was arrested Tuesday, with federal prosecutors saying he was taken into custody by the FBI in West Virginia.

Federal prosecutors allege that the eight suspects, who range in age from 19 to 32, were among nearly two dozen people conspiring to attack the White House's Freedom 250 UFC event on June 14, staged in celebration of the United States' 250th anniversary and President Donald Trump's 80th birthday.
