At least three people were killed after double-decker bus crashed into a bus stop in Stockholm on Friday, police in the Swedish capital said. 

In a statement, police confirmed that three other people were injured, two of whom were brought to the hospital by ambulance for treatment. 

The bus driver has been arrested and detained following a decision by the prosecutor, police said. 

Police initially said they were investigating the incident as manslaughter.

An update later on Friday night said there was "no indication that the incident was intentional" and that the "crime classification is causing death and causing bodily harm."

Police have still not commented on the gender or age of the victims.

What do we know about the bus crash in Stockholm?

Police said officers were working with rescue and ambulance services at the crime scene, which has been cordoned off.

According to Reuters, a spokesperson for Stockholm's rescue services said there were no passengers on the bus when it crashed.

The incident occurred shortly after 3 p.m. local time (1400 UTC/GMT) on Valhallavagen street, near the University of Technology.

A spokesperson from the company Transdev confirmed that the bus was one of theirs.

"It's one of our buses that was involved and it's a double-decker," Lovisa Abom said. 

Mathias Haglund of the rescue service said that the bus was "not supposed to be in service and that it was just the driver on board."

In a post on X, Sweden's Prime Minister Ulf Kristersson said his thoughts were with "those affected and their families."

"Police, ambulance, and rescue services now have a very difficult and important job to do. I urge everyone to show consideration and understanding for their tasks," Kristersson added.
