Observing vehicles
The police have been deployed to central Linköping due to a vehicle being noticed tooting at people and opening the car doors to seek contact. This has caused a reaction from the public who have called the police who have checked the vehicle.
It is a matter of a malfunctioning horn, and a vehicle that has broken down. The reason the driver opened the doors and sought contact with people is to inform that it was not done intentionally, which has drawn attention.
