FBI agents have arrested a man suspected in the bombing attempt during the Martin Luther King Jr. Day parade in Spokane, Washington.
Law enforcement officials are searching a home near Colville, north of Spokane, according to local television reports.
Evidence found inside the bomb were reportedly tied to that area. The FBI said the backpack contained two T-shirts, one from the 2010 Stevens County Relay for Life, an American Cancer Society fundraiser, and the other reading, "Treasure Island Spring 2009."
