It was just before 5 pm on Friday that the emergency services, ambulance and police were alerted to the accident at a small town in Värnamo municipality.
"It's a four-wheeler that should have rolled over in a slope," says Björn Öberg, press spokesman at the police.
On the quad bike an adult man and a smaller child should have traveled.
- According to the information we have now, none of them should be seriously injured, but they may go to an ambulance to hospital for control, says Björn Öberg.
Why the quad bikes have overturned in the hillside is unclear, but the police do not suspect any crime in connection with the accident.
