Search in Dorset under way for missing walker 26 March 2013 Last updated at 03:19 A major search has been started to find a walker missing in Dorset. The man, from Northern Ireland and in his 40s, is thought to be visiting the area to walk the coastal path. He failed to turn up to a hostel in Lulworth on Sunday night where he had been booked to stay. Portland Coastguard's helicopter has been checking caves around Lulworth and Swanage but nothing has been found. Anyone with information is being asked to call police. A coastguard spokesman said it was concerned for the man's welfare in light of the weather conditions, including a biting wind.
