The woman, believed to be around 20 years old, died after being hit on Stora Södergatan in the city centre by a bus full of children on their way to a school trip.
Police said they had launched a preliminary murder investigation.
“There are indications that she was pushed and that it was intentional,” said police spokesman Jacob Linton.
According to the police, the woman was walking on the sidewalk when she met a group of boys coming in the opposite direction.
A dispute arose and the woman ended up out on the street where she was run over by the bus.
