Police were alerted about the incident at 7:49 p.m.

"It is the public who calls in and tells about the abuse," says Fabian Hamnqvist, press spokesman at the Mittel police region.

The abuse was reported to have been carried out by one or more persons traveling on the bus.

- When the line bus arrived at the travel center, riot should have erupted between the bus driver and a bunch of young people, says Fabian Hamnqvist.

Unclear damage situation

When police arrived at the scene, most youths ran away.

- We got hold of some, partly with the help of security guards. They should be checked. We do not know who has abused the bus driver - if it was one or more, says Fabian Hamnqvist.

The bus driver's injury situation is not yet clear.

- He must have been talkable. An ambulance was sent to the scene, but it is unclear if he needed to go.

On Monday morning, the police had not yet arrested anyone.

A report of serious violence against an official has been prepared.
