The graffiti was daubed on a wall in Millennium Way near to the Caterpillar plant. Mr Dickson said it was “disgraceful” and appealed for anyone with information to come forward with it.
“This type of graffiti was designed to intimidate one particular section of our community when entering a certain area. But it has absolutely no place in our society and will not be tolerated,” he said.
“Those behind this graffiti are not representative of the vast majority of people, who will rightly find its message abhorrent. We are constantly working to make all parts of Northern Ireland open and welcoming to all, and sectarian graffiti such as this will not stop that.
“I would appeal to anyone with information on this disgusting incident to take it to police immediately.”
