A sorority in Pennsylvania is taking heat for a racist group photo.

The picture was taken of members of the Chi Omega sorority on the campus of Penn State.

The photo shows a large group of women during a racist Mexican-themed sorority party and has led to an investigation by the university, according to the independent Penn State blog Onward State.

The party took place around Halloween with the women dressed in stereotypical Mexican dress with sombreros and mustaches. There are two signs being held by some of the female partygoers. One of them reads "Will mow lawn for weed + beer" and the other states "I don't cut grass I smoke it."

After the picture was posted on social media sites like Facebook the women were identified as part of the Chi Omega sorority.

Cesar Sanchez Lopez, Vice President of the Mexican American Student Association, denounced the photo as a poor representation of Latin culture. He told the Penn State blog: "The Mexican American Student Association is disappointed in the attire chosen by this sorority. It in no way represents our culture. Not only have they chosen to stereotype our culture with serapes and sombreros, but the insinuation about drug usage makes this image more offensive. Our country is plagued by a drug war that has led to the death of an estimated 50,000 people, which is nothing to be joked about."

The photo has started an investigation into the party and the campus sorority.

A statement was made by the Penn State Panhellenic Council executive board to the Daily Collegian: "We are addressing the situation immediately with the members of the chapter in conjunction with their national headquarters."

Penn State's admissions statistics show that the undergraduate student body is comprised of 54 percent men and 46 percent women, but only 15 percent of the population have identified as being of color.
