Dortmund (dpa / lnw) - In Dortmund, a 42-year-old man was seriously injured in a violent altercation with a knife. He was then operated on, the police said on Monday.

On the station forecourt, he had previously clashed with a 34-year-old who probably came from the homeless milieu. The younger man then stabbed the 42-year-old's abdomen with a knife during the argument late on Sunday evening. Because this was emergency operated, danger to life can now be ruled out, it said. The 34-year-old was arrested and brought before the judge on Monday.
