Police patrols have been stepped up after a spate of racist graffiti in the past week.
There have been six incidents of homes and shops in the Heath and Mersey areas of Runcorn being targeted by racists.
Cheshire Police said there would be a high visibility presence in the areas to reassure the community.
Sgt Karen Jaundrill, of the community action team, said the incidents were linked as the same black spray paint had been used.
She said: "Racist and offensive graffiti of any kind is totally unacceptable and will not be tolerated by police, or the community.
"I would like to reassure members of the local community that patrols have increased in the Heath and Mersey areas of the town and positive action will be taken against anyone found causing criminal damage, or spraying graffiti of any kind."
