LONDON—Three British teenagers have been convicted for killing a policeman who was dragged behind a car for more than a mile after he confronted them over a stolen quad bike, in a case that shocked the country.
In August last year, the trio were towing the bike when approached by 28-year-old officer Andrew Harper who chased the group’s car, getting caught in the tow rope and being dragged for 1.4 miles (2.25 km) down a country lane.
