ARLINGTON, Texas — University of Texas at Arlington Police are investigating an allegation of sexual assault at the Kappa Sigma fraternity house this past weekend.

A female student says the assault occurred at the Kappa Sigma house on South Davis Drive at 1 a.m. Sunday. She reported the incident later that day.

In a written statement, UTA spokesperson Jeff Carlton said:  

"The University of Texas at Arlington Police Department is investigating an allegation of sexual assault reported Sunday afternoon by a female student involving a male student who is a known acquaintance. 

The incident originally was reported to the Arlington Police Department, but UTA police have taken over the ongoing investigation after determining the alleged incident took place on campus."

Calls and emails seeking a response from the fraternity and its national organization were not returned.

Greek life at UTA was already under the microscope

On April 1, the university suspended all fraternity and sorority social activities after multiple reports of hazing, alcohol violations and allegations of sexual assault.

“Due to recent allegations and concern for the well-being of our community…" the school said in a statement at the time, “all social activities of the Fraternity and Sorority life community are suspended.”

The university also announced the start of a Greek Life task force to “review the current state of affairs within our Fraternity and Sorority community and recommend steps to effect a positive shift in our campus culture."

But now another very negative shift with UTA police and the university concerned about both the culture and the latest criminal complaint.
