Anti-Semitic graffiti was found in a University of Wisconsin-Madison dormitory over the weekend, a campus spokeswoman said.
Meredith McGlone said swastikas were drawn on whiteboards of three Sellery Hall dormitory doors on Sunday.
McGlone said students from another college, who were visiting UW-Madison, drew the swastikas on three doors they selected at random.
She said UW-Madison takes campus climate seriously. The affected students are being provided information and support.
McGlone said UW-Madison officials will contact officials at the students' college to "provide information about the incident for any action that may be appropriate."
