The police report, made two months ago, says that emergency personnel refused to take the boy to the hospital. Instead, police drove him to the emergency room.
"This is really serious. We are going to investigate what happened," says Jörgen Tranevik, the head of the ambulance unit in Gävleborg County, to Swedish Radio news.
The boy had no physical injuries, but was extremely cold because he had sat on the ledge of the open window in the freezing cold.
