A sign on a private road in Weston was defaced with a spray-painted Nazi swastika symbol late Friday night or early Saturday morning, police said on Monday.

The act of anti-Semitic vandalism, which took place on Connors Lane, appears to be an isolated incident, police said.

"We haven't seen something like this for quite a while, and no other incidents like this were reported over the weekend," said police Detective Carl Filsinger.

The graffiti is under investigation, but there are no suspects yet. Filsinger added that the defacement did not appear to be directed at any particular individual.

If a suspect is charged, Filsinger said he or she could be charged with intimidation based on bigotry or bias. The State's Attorney Office would decide whether to file such a charge.

Filsinger said Weston police were also consulting with the Anti-Defamation League to monitor the situation. The vandalized sign, meanwhile, has been taken down.

"This is something we take very seriously," he added. "Hopefully, we can bring this to some closure soon so people don't worry about this type of incident happening again."
