Three Swiss teenagers have been charged with attempted murder and grievous bodily harm following a rampage on a school trip in Munich.
On June 30 the 16-year-old students from Küsnacht, canton Zurich, attacked five people within the space of half an hour.
The victims of their rampage included a 46-year-old man whom they nearly beat to death. They also attacked a disabled man and a Bulgarian student.
The head of Munich's homicide division said he was outraged by the brutality of the Swiss students, all of whom had previous convictions in Switzerland.
The two Swiss and one Slovenian had all been smoking hash and drinking – although they had less than one per mil alcohol in their system (roughly three drinks).
In Germany they face ten years in prison. In Switzerland the same crime would result in a prison sentence of up to only four years.
Following the events in Munich, the umbrella organisation for Swiss teachers demanded full transparency concerning students' previous convictions.
It is not known when the trial will start in Munich.
