A man is to face a court on Monday after a crowd of loyalist protestors attempted to cause disruption and block roads during the opening City of Culture concert in Derry/Londonderry.
Up to 150 people were involved in the protest at the Sons and Daughters event in the former military barracks in Ebrington Square on Sunday evening.
Police arrested two men and charged them with disorderly behaviour.
