The accident happened around 15:00 (14:00 GMT) on the Valhallavägen street in the Swedish capital. Police spokesperson Nadya Norton said the bus driver had been arrested and a manslaughter investigation had been opened as a matter of routine. Police said they were not commenting on the number, gender or ages of those affected at this time. Images in local media show rescue crews appearing to help people trapped underneath the double-decker bus. National broadcaster SVT quoted a communications manager at Transdev, which operates local bus services in north Stockholm, saying that the double decker belonged to the company. 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. (BBC)
