Far-right activists defaced a memorial statue in honor of slain prime minister Yitzhak Rabin on Wednesday, spray painting the words "Kahana was right" across the site.
Police have launched an investigation, and say two additional cases of Kahana graffiti were reported in the North on Wednesday.
The graffiti was condemned by Acre Mayor Shimon Lankri. "We will not allow for harm to be done to the coexistence among residents," Lankri said.
Acre was the scene of large-scale rioting between Jews and Arabs in 2008.
