SPOKANE, Wash. -- A man linked to a white supremacist organization was arrested Wednesday on charges that he left a sophisticated bomb along a Martin Luther King Jr. Day parade route in Spokane, raising concern in a region that was once a hotbed for hate groups.

Kevin William Harpham, 36, of Washington, made an initial appearance in U.S. District Court in Spokane on Wednesday and waived his right to a bail hearing.

He has been charged with one count of attempting to use a weapon of mass destruction and one count of possessing an unregistered explosive device in a case the FBI has called an act of domestic terrorism.

The federal complaint unsealed Wednesday provided no details of the investigation or what led to Harpham's arrest nearly two months after city workers found the bomb, which had been left in a backpack Jan. 17 and discovered before it could injure anyone.

An FBI affidavit made in support of the charges remained under seal, and a federal public defender assigned to represent Harpham said he did not know whether the government was pursuing other suspects in the case.

"The safety of our city has been of grave concern ever since Jan. 17," said Spokane Mayor Mary Verner, who expressed relief that an arrest had been made.
