A Saudi Arabian man studying computer security in Idaho was arrested Wednesday for visa fraud after authorities claimed he set up Web sites urging violence against the United States.

Sami Omar Al-Hussayen, arrested for visa fraud and making false statements, was taken into custody as the FBI conducted raids at several locations in Moscow, Idaho, home to the University of Idaho where the man studied.

Spokane, Wash. television channel KHQ-TV reported dozens of agents were serving search warrants in Moscow and the student was arrested at 4 a.m. at campus student housing. He was being held in the Latah County Jail.

Federal authorities were expected to release more details at news conferences scheduled for later Wednesday in Boise and Moscow.

"Yes, we have FBI and other police authorities on campus conducting some type of activity," said Jeff Olson, a university spokesman. "This activity took place as I understand it mostly in the married student housing on campus."
