It was in mid-October that the incident occurred. The two interns quarreled and one, a 42-year-old man, cut the other with a razor blade in his head and chest and neck.
There was a risk of the crime being completed, the prosecutor writes in the lawsuit, according to SVT Västernorrland.
The injured person, a 35-year-old man, managed to get away relatively easily. The 35-year-old was sentenced in 2012 to 18 years in prison for the murder of a motorcycle gang member outside Ronneby.
The intern who went to Blekingebon is now being charged with attempted murder.
