An officer was killed and four others seriously injured when two police helicopters crashed into each other during a riot training exercise above Berlin’s Olympic Stadium.
Both choppers were reduced to fiery hulks when they smashed into a field adjoining the stadium in heady snow.
As well as the serious injury and fatality media reports spoke of ‘many others’ being hurt. Each helicopter was carrying 25 police officers on a training exercise about crowd control: the Olympic Stadium from 1936 is now home to the Hertha Berlin Bundesliga football club
