Shortly before midnight on Sunday evening, the police and ambulance were called to Sidsjö in Sundsvall, where two people have been subjected to attempted murder.
The people were found outside and both were taken by ambulance to hospital for their injuries. The extent of the damage is unclear.
The police have cordoned off the crime scene and are working on investigative measures.
– We have cordoned off an area and are searching with a dog on site. We talk to people, hold witness interviews and try to form an idea of what may have happened, says Björn Pettersson, commanding officer at the police to TT.
