An employee at a clinic for disabled people outside Berlin was arrested Thursday on suspicion of killing four people at the centre and wounding a fifth, police said, with the motive still unclear.
The slain victims, two women and two men, were stabbed with a knife late Wednesday at the facility in the city of Potsdam, the capital of the eastern state of Brandenburg, the daily Bild reported.
Those killed are believed to be patients at the care clinic, local newspaper Potsdamer Neueste Nachrichten reported.
Police said earlier the dead were subjected to “intense, extreme violence”, but did not give any details around the circumstances of the killings.
A 51-year-old female staff member has been arrested on “strong suspicion” of carrying out the assault, police said, while acknowledging that any motive was still undetermined.
