CONCERN is growing for the safety of a 16-year-old boy who disappeared after the boat he was sailing in capsized in the freezing waters of Loch Lomond.

A police air-and-sea search for Stephen McCallum, of Kirkintilloch, has so far failed to trace the teenager who has been missing since 1am yesterday morning. His friend Stephen Smith, 17, who was also in the dinghy, managed to swim to shore to raise the alarm. Yesterday Inspector William Brown of Strathclyde Police, who is co-ordinating the search, said: "We are continuing an extensive search of the area." The boys had been camping with about 20 friends on the west shore of the loch near the holiday village of Tarbet.
