Knife attack at job center was announced on twitter

Bloody deed with announcement: the knife attack in the job center in rottweil had been announced by the suspected perpetrator on the internet. "I will kill a person of the job center tomorrow," the 58-year-old had spread in the short message service twitter.

This was said by the spokesman of the rottweiler prosecutor’s office, frank grundke, on friday. According to the investigation, the suspect had seriously injured a 50-year-old female employee with a knife during an appointment in an office on the seventh floor on thursday.

The woman was taken to a hospital by rescue helicopter and underwent emergency surgery. She could not be questioned at first. The suspected man with german citizenship was arrested without resistance at the job center. He had told the staff there after the attack that they could understand the police, he said.

Investigators recovered the murder weapon. A judge issued a warrant of arrest on friday – for attempted murder and dangerous bodily harm. The man has not yet commented on the accusations, the investigating authorities said.

If the police had been alerted to the tweet of the 58-year-old, it had immediately triggered an operation, said a spokesman. In such cases, the police immediately initiate "counter-measures and security checks". Police ask that such threats on twitter or other social media always be reported.

According to section 126 of the penal code, threats of serious bodily harm, robbery or murder can be punished with up to three years’ imprisonment. The man’s twitter account has since been blocked.
