Yempabou "Bubu" Palo has been suspended from the Iowa State University basketball team as he faces sexual assault charges.
According to a police report, Palo offered a woman ride home in the early morning hours on May 18, 2012 in Ames, Iowa. Instead of taking her home, he drove her to the house of his friend Spencer Cruise, and he asked the woman to come inside.
After the woman entered the house, she said she was sexually assaulted. Palo and Cruise "committed a sex act by force and against the will of the victim," the police report stated.
Ames Police Sgt. Rory Echer said that the woman reported the assault that same morning. Search warrants were obtained to collect DNA evidence. The Division of Criminal Investigations lab returned DNA results last week, Echer said.
DNA from both men was present on evidence collected during the investigation, the Des Moines Register reports.
"That's why the length of period, from May to now. We just recently got the test result of that," Echer told the AP.
The two men turned themselves in to authorities Friday morning.
ISU basketball coach Fred Hoiberg said he was "extremely disappointed" at the allegation.
