For the third day in a row, words like 'racist' and 'rapist' showed up spray-painted on fraternity houses on campus.

Earlier in the week, the Phi Gamma Delta (Fiji) and Pi Kappa Alpha houses were vandalized and were then joined by the Kappa Alpha and Kappa Sigma houses Wednesday.

University Police told KVUE's Jason Puckett that they had heightened patrols around the vandalized houses for the time being while they seek more information into who is responsible.

UT President Greg Fenves released the following statement about the graffiti Wednesday:

"At the University of Texas of Austin, we will not tolerate vandalism and threats targeting our students and are actively investigating the recent incidents near campus. Many students understandably feel concerned and vulnerable. I want them to know we are committed to making UT Austin a safe environment for all our students.

UT police are working with Austin police to add extra patrols to the neighborhood and review footage as part of a criminal investigation. The university has provided crisis support, advice and guidance to the students and groups affected by the incidents.. The Office of the Dean of Students is investigating, in accordance with the recently issued Hate and Bias Incident Policy. The incident has also been referred to the Campus Climate Response team."
