BERLIN (AP) — A prominent Berlin politician was violently assaulted and suffered injuries to her head and neck, police said Wednesday, in the latest attack on elected officials that raises concern over rising political violence in Germany.

Frankziska Giffey, the city’s top economic official, a former mayor and an ex-federal minister, was attacked at an event in a Berlin library on Tuesday by a man who approached her from behind and hit her with a bag containing a hard device, police said.

Giffey was taken to a hospital and treated for head and neck pain, police said. Berlin prosecutors said Wednesday morning that they had identified the alleged perpetrator, but did not give details.

Berlin Mayor Kai Wegner strongly condemned the attack.

“Anyone who attacks politicians is attacking our democracy,” said Wegner, according to German news agency dpa. “We will not tolerate this. We will oppose all forms of violence, hatred and agitation and protect our democracy.”
