A 59-year-old man was arrested after paint was thrown and a racist slogan erected at a house in Co Down.
The attack - which is being treated as a hate crime - happened in Dunbeg Park, Hillsborough on Thursday night.
Paint was thrown at the door, and a racist slogan placed on it.
PSNI Lisburn inspector Paul Wright said:
"The man was arrested following a report of criminal damage at residential premises at the Dunbeg Park area of Hillsborough at around 10.20pm on Thursday August, 21.
"It is believed that white paint was thrown at the front door of a house in the area, with a racist slogan placed on the door. The slogan has been removed and efforts have been made to remove the paint."
The man arrested has since been released on police bail pending further enquiries.
