There also were two forcible sexual offenses reported in 2009 and one in 2008.
Given the rarity with which sexual offenses have reported on campus in the past, UCO officials are alarmed that two incidents have happened within a month, said UCO spokesman Charlie Johnson.
Johnson, who has worked at the university for 12 years, said he can't remember another instance in which two sexual offenses were reported so closely together.
University officials plan to distribute leaflets with information on sexual assault, particularly among acquaintances, Johnson said.
The university is also requiring dorm resident assistants to hold floor meetings to address the issue of sexual assault.
