The toddler was rushed to hospital with head injuries where his condition was described as "critical" according to local police. He had been watching the game between Villa and Sirius with a relative in the media grandstand when the accident occurred.
"The attention was on the hockey game and the boy slipped off backwards. There is a fence there that is high enough but the lowest strip of wood is about 50 centimetres so as he is only three years old he was easily able to get underneath it," Tomas Vänerfors of the Lidköping police told the TT news agency.
Moments later the boy fell an estimated five metres and the alarm was raised by a spectator. The bandy match was abandoned as medical services arrived on the scene to treat the boy for his injuries whom police said was conscious in the immediate aftermath of the accident.
"One of my colleagues heard how the boy screamed but the rest said it didn't look good. I don't know exactly what kind of injuries he has but there are head injuries," added Vänerfors.
The boy was taken to hospital in Skaraborg and later transferred Sahlgrenska University hospital in Gothenburg. It remains unclear exactly how the accident happened as nobody witnessed him falling over the edge onto the concrete floor behind the grandstand.
"His condition is critical according to the hospital," said Vänerfors who added that the police will not be not investigating the matter. Foul play has been ruled out and there is no suspicion a crime has been committed.
