Former German President's son knifed to death

BERLIN, Nov 20 (AP): The son of former German president Richard von Weizsaecker was stabbed to death while he was giving a lecture at a hospital in Berlin where he worked as a head physician, police said Wednesday.

A 57-year-old man is in custody after a man jumped up from the audience at the Schlosspark-Klinik and attacked Fritz von Weizsaecker with a knife on Tuesday evening. Another man who tried to stop the attack was seriously wounded.

"We cannot yet say anything about the attacker's motive," said police spokesman Michael Gassen, adding that the suspect is still being questioned.

Von Weizsaecker died at the scene despite immediate attention from colleagues.

The 59-year-old was the son of one of Germany's most esteemed presidents, who was the country's head of state - a largely ceremonial post - from 1984 to 1994. The former president died in 2015.
