December 1, 08:09, Violence/threat against public official, Stockholm

A man in his 50s sprays with a fire extinguisher on board a bus. Several passengers call the police and the bus remains standing on Skansbron where it blocks the traffic.
The bus driver has been attacked with the fire extinguisher but neither he nor any passenger has suffered any injuries. 
The public follows the identified perpetrator so he does not get to go very far from the scene before a patrol can pick him up and arrest him. 
The police initiate an investigation into assault on a public official.
