A policeman has been praised for diving into the River Wear to save a drowning teenager.

Traffic policeman David Morgan, 32, a former international polo player, braved the water to rescue a 19-year-old who had fallen 30ft from Framwelgate Bridge in Durham City at about 11.30pm last night.

The officer swam more than 20 yards to reach the youth who had disappeared under the water several times.

The youngster, who had apparently climbed on to the side of the bridge during a night out, was detained at the city's University Hospital for observation.

Chief Inspector John Bell said: "PC Morgan's unselfish bravery was highly commendable and was undoubtedly instrumental in averting a potential tragedy.''
