Police at the University of Maryland, College Park are investigating "two incidents of bias and hate," President Wallace Loh said in a Wednesday e-mail to the campus.
Loh said an elevator in an academic building was vandalized with anti-Semitic messages and that a campus facilities supervisor found a noose hanging in a space that was being renovated.
A spokesman for the campus police said investigators believe the incidents, one discovered Saturday and the other Monday, are unconnected. But police have no suspects.
Loh wrote that on-campus incidents of bias and hate have decreased from 33 in 2003 to five in 2011 but added that "even one incident is too many."
