Grounds crew workers at the Crystal Lake Golf Club in Lakeville found a large swastika etched into one of their greens Monday morning as they tended to the course.

According to Golf.com, mowers discovered the anti-Semitic symbol "gouged into the turf."

After the incident was reported to police, workers were quick to get rid of the symbol before golfers were able to notice.

On Wednesday, an attendant at the pro shop acknowledged the incident to Golf.com and "made it clear that this behavior was unwelcome at Crystal Lake.

"We see it as most likely some kids out there vandalizing, but we don't know who or what it was," the attendant told Golf.com. "You know, this is a great place and we don't want to make a big fuss over it, really."

On Facebook, the golf club apologized to "anyone who has had to view the image in the press."

"We would like to firmly state how hurt and saddened we are that we were the victim of such a crime. We, in no way, stand for anything remotely related to that symbol, and we hope that swift justice is brought to the perpetrator(s) of this crime," the club said in the Facebook post.

In a statement Wednesday evening, Steve Hunegs, executive director of the Jewish Community Relations Council of Minnesota and the Dakotas (JCRC), asked anyone with information to call police.

"We are deeply concerned by this incident," Hunegs said.
