Campus cop praised for downing Ohio University knifeman

A police officer has been praised for shooting dead a man who drove his car into a crowd at Ohio State University and began to stab people with a butcher's knife.

Officer Alan Horujko, 28, who started on the Columbus university's police force in January 2015, was responding to reports of a nearby gas leak when the car mounted a campus kerb at 9.52am on Monday.
