Investigations are ongoing

By mid-morning, the injured man was out of mortal danger, according to police. The police initially provided no further details on the exact motive for the crime or the relationship between the suspect and the victim. A police spokesperson told the APA only: "They were not related, as a police spokesperson told the APA."

The investigation has been taken over by the Vienna State Criminal Police Office, Southern Branch. The 17-year-old, a Russian national, is currently being held in police custody. Nothing has been revealed about any other possible accomplices or backgrounds for the time being.

The incident occurred on the night of Monday, June 1, 2026, in a residential building in Vienna-Liesing. The police did not specify exactly when the crime took place. The exact circumstances of the argument are the subject of ongoing investigations.

Legal classification

The case is now being handled by detectives from the Vienna State Criminal Police Office, Southern Branch. They are conducting interviews at the scene and securing evidence, among other things. The interrogation of the 17-year-old is also scheduled to take place on Monday.

There is currently no information on how the suspect obtained the kitchen knife. The police remained tight-lipped on this matter as well. In general, in Austria, carrying and using such items can be classified as assault or attempted murder if a person is injured with them.

The Vienna Public Prosecutor's Office will likely decide on any pre-trial detention or further measures in the course of the proceedings. Until then, the 17-year-old will remain in police custody. Authorities pointed out that the victim's health condition must continue to stabilize before more precise statements can be made.
