After police officers smashed through one of the car’s windows, they found the boy in an exhausted state but still conscious. The child was rushed to hospital.
At the time of the incident, 6.30pm on Friday, the temperature was 27C in the shade.
“When the police came, they said the windows were all the way up and that the child was sweaty, warm, and didn’t seem to respond to them,” Mats Nylén of the Örebro police told the TT news agency.
Emergency staff at the hospital said that the boy’s condition was “not critical” and that he got back to his senses after drinking some water.
The parents, who were shopping in a nearby store at the time, have both been reported for putting the child in danger, and social authorities have also been called in.
The incident is not the first of its kind in Sweden recently, with a man in Eslöv forgetting his son in a car in May. The child was found dead eight hours later.
The man was given a suspended sentence for manslaughter, avoiding both a fine and imprisonment, with the chief prosecutor saying afterward that the suspended sentence served “as a warning”.
