Sinn Fein leader Mary Lou McDonald has called for public anger to be directed at the Government instead of refugees.
She was speaking after a poll in the Irish Independent found 56% of the public believe Ireland has taken in too many refugees in the past year. Protests have been held in Waterford, Cork and Dublin in recent weeks.
Gardai are also investigating an alleged assault at a campsite in Ashtown, Dublin, where migrants had been living for months, and a suspected arson attack on a disused school in Dublin that had been rumoured to be used for migrants.
