“There was some sort of scuffle, and then a knife came out,” said Bjarne Andersson of the Värmland police.
The clash involved two families in a store in the industrial area of Våxnäs outside of Karlstad.
In addition to a knife, a sword was also involved in the fight.
“Apparently it's called a samurai sword. It was a very large sword. It was never taken out of its sheath but was still used as a weapon in the fight. It seems the sword was in the store,” said Andersson.
The three victims were taken to the central hospital in Karlstad with mild injuries.
Police are still investigating the cause of the fight.
