Update: He's arrested
ROLLA, Mo. (AP) _ Nearly two dozen people were being decontaminated Tuesday after a white, powdery substance was found on a student who claimed to have a bomb and threatened ''terrorist-type'' actions at the University of Missouri-Rolla, officials said.
The man, described as an international graduate student depressed about his grades, also claimed to have anthrax, according to police. School officials said ''possible bomb materials'' were found when he was taken into custody.
Twenty-three people were sent through a decontamination process Tuesday morning outside the university's civil engineering building, where a police standoff with the student had started around 2:30 a.m.
Acting Police Chief Mark Kearse said that when police arrived the student was holding a knife and that he held up a bag and said: ''This is a bomb.'' He also claimed to have anthrax.
