On Wednesday, the police went to a large-scale operation at a vocational college in Dortmund, where a student was injured in an attack.

A perpetrator was arrested, another on the run, said a police spokeswoman. When asked, she emphasized that it was not a rampage. Further details were initially unclear. The “Ruhr Nachrichten” had previously reported on it.

The media reported a “knife attack”. The police spokeswoman initially did not confirm this. A knife handle was found, but it was not known whether it was an act of crime. The police are still in the school, the Paul Ehrlich Vocational College in the Hacheney district. The search for the second suspect continues.
