Authorities responded to reports of antisemitic flyers littered across Highland Park and other North Shore communities Thursday morning.

The flyers, which contained antisemitic hate speech, appeared in neighborhoods on Yom HaShoah, the Day of Holocaust Remembrance, according to Highland Park police.

“This activity is a continuation of an ongoing effort to stoke hatred and mistrust throughout Illinois and the nation,” Highland Park Mayor Nancy Rotering wrote in a Facebook post.

Highland Park will work with other suburban police departments and the FBI to investigate the flyers.

Officials have not released any additional information on the flyers found on the North Shore.
