Police siren helps find two lost walkers in Mourne Mountains 8 September 2013 Last updated at 16:37 A police siren has helped rescuers find two men who became lost while walking in the Mournes area of County Down. They lost their way near Annalong Forest at about 22:15 BST on Saturday and called police for assistance. A police helicopter, search and rescue co-ordinators (SAR) and the Mourne Rescue Team were called in to help. SAR found the pair three hours later. Their location was tracked by using a PSNI vehicle siren and phoning the men's mobile to confirm they heard it. The PSNI vehicle was in the Quarter Road area when the walkers said they could hear the siren. The pair were discovered safe and well shortly after 01:00 BST on Sunday and were then able to make their own way home. Local knowledge The PSNI Area Commander for Newry, Ch Insp Davy Beck, said: "The safe rescue of the two men was made possible by the close working relationship between police and the rescue organisations. I am in no doubt that the excellent local knowledge and initiative of the officers involved was a key part in the successful rescue operation and I am pleased that they were able to assist in this incident resulting in the two men being found safe and well. The two men had been taking part in the Mourne Wall Walk, a 22-mile journey along the granite wall that lines the mountainsides. In advance of the event, participants were warned that it is a "challenging mountain route" and that they must be "prepared both in terms of physical fitness, skill and equipment." The Mourne Heritage Trust and the Mourne Rescue Team were among the charities that benefitted from funds raised by this year's walk.
