A woman has been arrested after four people died in what police described as a violent incident at a hospital near Berlin.
Police arrived at the Oberlin Clinic late on Wednesday and arrested the 51-year-old suspect, according to the report.
A police spokesman was quoted as saying that the deaths were "the result of violence”.
He confirmed that four people had died and that another was seriously injured.
The Oberlin Clinic is a specialist orthopaedic hospital based in Potsdam, the capital of Brandenburg, the state that surrounds the German capital.
It has some 160 beds and 300 staff, according to its website.
It was unclear if the dead were patients at the clinic and there was no information regarding a motive.
Police in Brandenburg said the woman detained on suspicion of the attack is an employee at the clinic.
"The victims showed signs of significant external violence," police spokesman Thorsten Herbst said.
Police were still investigating the exact circumstances but said the detained woman was "urgently suspected" of the killings.
Local newspaper Potsdamer Neueste Nachrichten reported the victims were residents of the Thusnelda von Saldern House, which cares for people with serious disabilities.
