Graffiti praising the murder of PSNI constable Ronan Kerr and threatening further attacks was daubed on walls in Derry’s Bogside this week.
One of the slogans read: “GAA cops, look what use [sic] got” - a reference to Constable Kerr’s membership of a Co. Tyrone GAA club.
The graffiti was later painted out by community activists and condemned by local politicians and churchmen.
Constable Kerr was killed when a booby-trap bomb exploded underneath his car in Omagh on Saturday last.
Dissident republicans have been blamed for the attack.
SDLP Foyle Assembly candidate Pat Ramsey said it was the second day that such “despicable and disgusting” slogans had appeared.
He said: “People really are outraged by this.
“This is not indicative of the feeling among the people of the Bogside and that is why those responsible skulked around in the dark of night and did their deed.
“They are not standing up and saying it, they are using the same cowardly tactics of those who callously murdered PC Kerr.
“The people of the Bogside are angry this morning, they have been angry since Saturday, just like the rest of the North.
“They do not deserve to be tarnished with this and the good name of PC Kerr does not deserve to be tarnished like this.”
This was a view echoed by Derry’s Church of Ireland Bishop Ken Good.
“The strong reaction from the citizens in the Bogside and across our city has demonstrated that the sentiments expressed in some graffiti are wholly unrepresentative of the community,” he said.
“Rather they are the views of an increasingly isolated number of misguided individuals.
“The united voice of the community has been more accurately expressed in the strong lead given by politicians, churches and sporting organisations, not least the GAA, in outrightly condemning the killing of Constable Ronan Kerr.”
Constable Kerr’s funeral took place on Wednesday and was attended by the North’s First and Deputy First Ministers, Peter Robinson and Martin McGuinness, as well as Taoiseach Enda Kenny.
