MINNEAPOLIS (AP) - Several students demanding greater on-campus racial and ethnic diversity have taken over University of Minnesota President Eric Kaler's office.

University spokesman Steve Henneberry says 10 to 15 students were in Kaler's second-floor office in Morrill Hall on Monday "having a conversation with the president and other senior leaders."

Henneberry says that Morrill Hall was locked and anyone needing to enter the building had to show identification.

The action began around noon and continued into the evening. No arrests have been reported.

The university released a statement expressing support for free speech rights and saying how the school has so far addressed areas of concern.

The protesters' demands include greater racial and ethnic diversity in university hiring practices and more money for the school's ethnic studies program.
