Dharamshala, Sep 21 (ANI): Police called off the fifth unsuccessful search operation to trace the two French trekkers who went missing last year in the mountains of Dharamshala in Himachal Pradesh and remain untraceable. Valentin Marcel Gorges and Francois Xavier Camille trekked to Tirund Hill in the city on August 22 last year with a group of 32 members. The two went missing after they decided to trek further to scale Moon Peak and separated from the group. Several teams of the state police, National Disaster Response Force (NDRF) and Army helicopters conducted a month-long massive manhunt and scoured the Dhauladhar hills but remained unsuccessful in tracing the missing duo. The search was resumed on September 16 by a 27 member team comprising mountaineering experts, state police, local trekkers and the Indo-Tibetan Border Police (ITBP).
