The statement said that between February and September last year, campus police were called five times to deal with disruptions Loughner caused in classrooms and libraries. On Sept. 29, the college said, it discovered that Loughner had posted a YouTube video he had made on the campus.
"In the video, he claims that the College is illegal according to the U.S. Constitution, and makes other claims," the college's statement said.
On Oct. 4, during a meeting with Loughner, his parents and college administrators, he agreed to withdraw, the college said.
School officials told him he could return only if he obtained a clearance certifying that "in the opinion of a mental health professional, his presence at the College does not present a danger to himself or others." Tucson shooting suspect Jared Loughner appears to have posted bizarre messages
