Dozens of students at Baraboo High School are seen making an apparent Nazi salute in a group photo.

A Wisconsin school district is investigating a photo that shows a group of high school boys apparently making the Nazi salute. A school official denounced the image on Twitter –– and said it would pursue legal actions if necessary.

Baraboo Superintendent Dr. Lori Mueller says she became aware of the photo, which shows more than 60 male students dressed in suits with their right arms extended upward, on Monday after it was posted on social media and received immediate backlash.

"The photo of students posted to #BarabooProud is not reflective of the educational values and beliefs of the School District of Baraboo," she said in a statement. "The District will pursue any and all available and appropriate actions, including legal, to address."

Mueller says the photo appears to have been taken last spring and wasn't on school grounds. Baraboo police are also investigating.

She added, "the Baraboo School District a hate-free school environment where all people…are celebrated and respected."

A photographer with Wheel Memories took responsibility for taking the controversial snapshot at a prom event and offered an apology.

"It is too bad that there are those in society who can and do take the time to be jerks; knowingly and willingly to be jerks!" the post on the the company's website read. "To anyone that was hurt I sincerely apologize."

CBS News reached out for further comment.

The Auschwitz Memorial tweeted about the photo, "This is why every single day we work hard to educate. We need to explain what is the danger of hateful ideology rising. Auschwitz with its gas chambers was at the very end of the long process of normalizing and accommodating hatred."

It is so hard to find words…
