Sinn Féin has been criticised by other Stormont parties for not signing a joint statement in response to the removal of Prison Service recruitment posters.
Political leaders from four of Northern Ireland's main parties released a statement opposing intimidation of prison officers and the PSNI and offering "full support" for recruitment campaigns.
It was in response to an online video showing Prison Service recruitment advertisements being removed from a bus stop in Derry by members of a republican group.
