COMMACK, N.Y. (CBSNewYork) – An investigation is underway on Long Island after two Commack High School students were photographed wearing t-shirts with anti-Semitic messages.

As 1010 WINS’ Carol D’Auria reported, the photo shows two students in red t-shirts emblazoned with large, black swastikas with the word “Auschwitz” in large letters. In smaller letters, the words “hit the showers” can be seen, D’Auria reported.

The photograph is from an incident occurring off school grounds, however the Commack School District confirms the students pictured attend its school.

The photo, which also appears to show the two students participating in underage drinking, was posted on Twitter, 1010 WINS reported.

“I don’t know why they would ever post that, that never goes away. I don’t support what those kids did at all,” Commack High School senior Alex said.

The school district said the students are being disciplined.

Just last September, five students from the same high school were photographed on campus with t-shirts spelling out the word “rape.”
