Swedish police say no information the Stockholm bus accident was an attack, without giving numbers of those killed.

Several people have been killed and injured when a bus hit a bus stop in central Stockholm, Swedish police said, adding that they had no information pointing to it being an attack.

There were six casualties in the incident on Friday, a spokesperson for Stockholm’s rescue services said, without giving the numbers of those killed and injured.

The spokesperson said there were no passengers on the bus at the time.

“It is being investigated as involuntary manslaughter. The bus driver has been arrested, but that is routine in such an incident,” a police spokesperson said.

Health authorities spokesperson Michelle Marcher told the AFP news agency that two seriously injured people had been transported to hospital.

Police said that several people were hit, but they were not immediately providing information on their number, gender or ages.

Ambulances, police and rescue services were working at the scene, they added.

A picture on daily Aftonbladet’s website showed emergency services at the site, surrounding a blue double-decker bus, with debris scattered around the vehicle.

The incident occurred near the Royal Institute of Technology university, police said.

‘Unreal’

A woman identified as Michelle Mac Key told the daily newspaper Expressen she stepped off another bus at the scene just after the accident happened.

“I crossed the road and saw the double-decker bus that had mowed down an entire bus stop queue,” she said. People were screaming and trying to help the injured.

She said she saw both injured and dead people lying on the ground. “There must have been more people under the bus,” she said.

A nurse by profession, she and another man who was a doctor, offered their help to police when they arrived.

“They told us to stand next to the dead bodies,” she said. “I thought it was an exercise at first. That maybe they were dolls. It was so unreal. Chaos.”

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

“I have received the tragic news that several people have died and been injured at a bus stop in central Stockholm,” he wrote on X.

“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.”
