Officers had surrounded him after reports of a man acting strangely
They tried to persuade him to drop the knife but he began cutting himself
He was shot when he moved towards an officer who went to stop him
Shocking video footage has emerged of the moment police shot dead a naked man brandishing a knife in a landmark fountain in Berlin today.
The man was shot once after being surrounded by officers at the German capital's Neptune Fountain, close to the city hall.
Police tried to persuade the man to put the knife away but instead he started cutting himself.
As a policeman climbed into the water to try and stop him, he moved towards the officer and was shot.
The footage appears to show the man walking towards an armed police officer who is heard shouting at him.
