Students are planning to rally Monday afternoon to protest an alleged attack on three black students at University at Albany State University of New York by a group of white people. Three women called campus police shortly after 1 a.m. Saturday and said they had been attacked by a group of 10 to 12 white men and women on a bus who shouted racial slurs. The initial call came from a dorm, and campus and city police are jointly investigating what happened and where, said Steve Smith, a spokesperson for the Albany Police Department.
