Storefront windows in London's downtown were vandalized with antisemitic graffiti in recent days, prompting police to launch an investigation and the mayor to condemn the act.

Swastikas and other symbols were spray painted onto windows and doors on Carling Street, a tiny road between Richmond and Talbot streets.

Some of the storefronts appeared to be empty and one was for lease. .

London police said Tuesday they had received calls about property damage and were investigating. Later, Police Chief Steve Williams made an appeal on social media for public information.

"We are actively investigating. We strongly condemn this hateful and hurtful act and appeal to anyone with information to contact police or Crime Stoppers," Williams said on Twitter.

Mayor Ed Holder pointed to International Holocaust Remembrance Day which was marked last week.

"The grotesque acts referenced below demonstrate why such occasions are as relevant as ever, including here in #LdnOnt," the mayor wrote on Twitter Tuesday night.

"We stand in solidarity with our Jewish friends, neighbors, and colleagues - now and for always," Holder added.
