Homes evacuated in Denbigh devices search 20 April 2013 Last updated at 08:25 As many as 40 residents from an area of Denbigh in north-east Wales spent the night in a town hall after their homes were evacuated by police. It followed the earlier arrest of a 46-year-old man after a spate of firework-like attacks in the town. Explosive experts were called in to assist North Wales Police with a search of an address in the town. The evacuation of properties in Lenten Pool was a safety precaution and residents have since been allowed home. The operation on Friday followed a series of attacks involving what are thought to be homemade firework-type devices. There have been more than a dozen separate incidents in the town since March, damaging cars and smashing some windows. Safety checks A spokesperson for North Wales Police on Friday night said that ordnance experts from Chester were called in to assist with the search of a property linked to the arrest on Friday. The 46-year-old man is currently in custody while he is questioned at St Asaph. The spokesperson added: "Safety of the public is of paramount importance, and we apologise for any disruption. We are grateful to the residents for their understanding and co-operation.
