WILMOT TOWNSHIP -- Police are investigating after reports of racial and hate-motivated posters being circulated in Wellesley Township, Wilmot Township and Kitchener.

The posters include messages promoting White Lives Matter.

The Mayor of Wellesley Township Joe Nowak says his wife found one of the posters on a mailbox while out for a walk Thursday morning. He reported the sign to the police.

"I was thinking at the time just to pull them off because they are disgusting, but I was told maybe that's not a good idea, wait for the police to come and let them have a look at them," he said. "We are so much stronger because of the diversity out here and it just saddens me to see something like this happen, and it saddens the whole community."

Nowak added other councillors checked their wards for other posts and none were found Thursday.

"It's not a matter of expressing an opinion, it was an incitement to violence," said Wellesley Township councillor Peter van der Maas.

The councillor adds that he posted about the incident on social media and received feedback from more than 1,500 accounts, with almost unanimous condemnation of the poster.

Similar posters have been found in Wilmot Township and throughout Waterloo Region in the past month.

Waterloo regional police are urging anyone who finds a poster not to destroy it as they could be destroying evidence.

Anyone with information is asked to call police or Crime Stoppers.
