MINNEAPOLIS — Vandals defaced a sign promoting the University of Minnesota’s Muslim Students Association.

Someone scrawled “ISIS” over a hand-painted mural on a bridge connecting the east and west banks of the Twin Cities campus. The acronym is a reference to the Islamic State group.

The Minnesota chapter of the Council on American-Islamic Relations is calling for a hate crime investigation. Executive Director Jaylani Hussein said the vandalism is among a number of recent actions targeting Muslims.

According to a press release, the Muslim Student Association also condemned the graffiti and demanded action from the university.

University President Eric Kaler’s office issued a statement calling the graffiti an abhorrent action “that will not be tolerated on our campus.”
