A University of Wisconsin-Madison student was accused of sexually assaulting another student last fall.
The UW Police Department said a 22-year-old UW student was driven to the department by a local food delivery driver on Oct. 25. The woman had asked the worker for a ride saying she needed help. She had been sexually assault outside.
Officers assisted the student with medical attention and began an investigation, police said.
UWPD said investigators worked with the delivery driver, the victim, Madison police and other community members to piece together the events of the evening and identify a suspect.
Kenneth M. Plaisted, 20, of Cedarburg, was arrested on suspicion of sexual assault, UWPD said Friday.
UWPD said DNA samples from the evidence connected Plaisted to the case.
