MINNEAPOLIS — Police say they’re investigating another sexual assault at a University of Minnesota fraternity.

Authorities say it happened at the Chi Psi fraternity Saturday night. The victim told police she woke up the following morning with serious injuries, went to the hospital, but doesn’t remember what happened to her.

The assault happened two blocks from an attack the weekend before at the Delta Kappa Epsilon fraternity.

The university issued a crime alert to students Monday night, warning them of the consequences of excessive drinking and suggesting the buddy system when going out.

Police tell WCCO-TV there’s no reason to believe the two attacks are related. No arrests have been made.
