Several people have been killed and injured after a bus crashed into a bus stop in central Stockholm, Swedish police say.

Circumstances surrounding the crash around 15:23 (14:23 GMT) on the Valhallavägen street in the Swedish capital remain unclear.

Police spokesperson Nadya Norton said the bus driver had been arrested and a manslaughter investigation had been opened as a matter of routine.

It is not clear if there were passengers on board. Police said they were not commenting on the number, gender or ages of those affected at this time.

The incident occurred near the Royal Institute of Technology university.

Images in local media show rescue crews appearing to help people trapped underneath the double-decker bus.

A witness who owns a shop on the street told SVT that the bus hit a pole in front of the bus shelter. They said several people ran into the shop crying.

A woman told the local Expressen newspaper that the bus “mowed down an entire bus stop queue”.

She said that people were screaming and trying to help the injured, while dead people lay on the ground.

“There must have been more people under the bus,” she said.

Prime Minister Ulf Kristersson said his thoughts were with the victims and their families.

“People who might have been on their way home to family, friends, or a quiet evening at home. We do not yet know the cause, but right now my thoughts are primarily with those affected and their loved ones,” he posted on X. (BBC)
