Black paint daubed on the walls and the word 'collaborators' painted at the Sinn Féin office in Derry.
The vandalising of a Derry Sinn Féin office has been condemned.
The party's Eastway office in Creggan was targeted by members of the group Éistigí.
Éistigí is the youth wing of the dissident republican party, Saoradh.
Black paint was daubed on the walls of the Sinn Féin constituency office, with the words 'collaborators' painted on the ground outside.
On a post on Facebook, Éistigí stated that its members targeted the office following a recent leaflet drop in the Greystone estate in Antrim by the PSNI and Sinn Féin representatives.
The post stated: “No true Republican should need the armed wing of the British state to engage with the people of Ireland.
“The PSNI—an institution built on oppression and colonial rule—cannot be “reformed” or “rebranded” to serve Irish interests.
“Yet, Sinn Féin continues to legitimise them, standing shoulder to shoulder with those who enforce British rule in Ireland.
This is not the work of those who claim to stand for a united Ireland. It is the work of those who have traded principles for political expediency, who have embraced normalising British rule rather than resisting it.
“Those who fought and died for Irish freedom did not do so to see so-called Republicans working hand in hand with the forces of occupation.”
Sinn Féin North Belfast MLA Gerry Kelly said: “This wanton act of vandalism will not distract Sinn Féin from the work we do in the community as we work towards building a better future for all in a united and sovereign Ireland.
“Those involved in this vandalism have no support and nothing to offer.”
The PSNI said they are aware of the incident and enquiries are ongoing.
