“We’re not talking about a hate crime at the moment, just about attempted murder,” local police chief Sven Holgersson told Swedish broadcaster SVT, according to TheLocal.se website.
“Based on the way things are looking right now, it’s an isolated incident.”
The victim’s condition was said on Wednesday to be in a serious, but stable condition in hospital.
She was a part of Helsingborg’s small Jewish community, reported to include around 100 members.
Some Swedish press reports suggested the suspect’s mental health may have been a factor in the attack. He was arrested by Danish police early on Wednesday morning after fleeing across the border from Sweden.
