The police do not want to comment on what prompted the police operation at this time. 

- No, I can not go into any further details.

I can confirm that we were on site outside the bus station at 9.20 pm last night, that we blocked off the site and that one person was taken to hospital by ambulance.

No person has been detained, and now the preliminary investigation leader is working on the case.

That's what Björn Pettersson, RLC officer with the police, says.
