Just before 8 p.m., the police and ambulance services were called to a grocery store on Stora Nygatan outside Kalmar.
The reason is a fight that broke out in the store.
“A man with a stab or cut injury is being treated by paramedics,” the police write on their website.
The store is emptied of staff and customers and is to be cordoned off for a crime scene investigation, the police write.
One or more perpetrators are being sought and no one has been arrested. The incident is currently being investigated as attempted murder.
