'Zombie d**** ahead': Someone hacked a traffic sign in Canada to display NSFW warning

Updated: 

The small Canadian town of Stittsville, Ontario has gone viral on social media - but perhaps not for reasons the residents will like.

Local road users have been the unwitting victims of an alleged hack to a traffic sign near the town.

The NSFW sign warned drivers of "zombie dicks ahead!"

Matt Sweeting, who posted a clip of the warning on Instagram, called the hack "modern vandalism".

Local police told the Ottawa Sun that they would not investigate unless they received a complaint.
