A flag was stolen and sinister graffiti daubed on the wall of the home of a Protestant family living in Coleraine.
Sometime in the early hours of Saturday morning, an Orange banner was taken from the house in the Greenmount area and the words “We’ll be back” smeared on the wall of the house.
DUP East Londonderry MLA Adrian McQuillan condemned the incident and has appealed for information.
He said it is the latest of a series of similar attacks in the area and claimed that a number of homes where Unionist flags are displayed have been targeted.
“I totally condemn this attack on a family home at the weekend where an Orange Standard on display outside the house was torn down and graffiti dubbed on the wall of a threatening nature,” he said.
“This is part of a series of attacks on homes in the local area. I appeal for calm and for them to stop immediately.
“I also appeal for anyone with information to come forward to the PSNI in order to catch those responsible and bring them before the courts. No one should be subjected to such intimidation and sectarianism by those who are intent on spreading hate.”
Mr McQuillan has urged the PSNI to step up patrols in the area as he says tensions and fears have been raised.
A spokesman for the PSNI said police are investigating reports of criminal damage to the house sometime overnight between Friday July 26 and Saturday July 27.
“It was reported to police that graffiti had been painted on the wall of a house in the area,” he said.
Police are appealing to anyone who may have witnessed the incident or has any information to contact them at Coleraine on 0845 600 8000 or call Crimestoppers in confidence on 0800 555 111.
