Berlin police have shot and wounded a 53-year-old Austrian man who allegedly waved a knife inside a cathedral in the centre of the German capital.
There was no indication the man’s actions were linked to terrorism, Berlin police spokesman Winfrid Wenzel said.
The dpa news agency quoted police as saying the man appeared to be confused.
Cathedral employees called police and dozens of people were evacuated from the holy site.
One of the two officers responding to the call opened fire, wounding the man, Mr Wenzel said.
Both the suspect and the police officer were taken to hospital. Dpa said the officer is in serious condition.
The area around the cathedral is typically crowded with tourists and visitors, particularly on Sunday. A Sunday evening prayer service at the church was cancelled.
