The chair of the Ulster Unionist Party’s Foyle Constituency Association condemned those behind the incident which caused the evacuation of homes and premises - including the local UUP office - on Wednesday afternoon.
Ronnie McKeegan said: “Once again, residents and business people in the city of Londonderry have been put in physical danger and been inconvenienced by faceless people whose only aim is to cause disruption and who have nothing positive to offer anyone in this city or this society. There’s no excuse for planting devices or creating circumstances where people have to leave their homes and businesses.”
