Police have opened an investigation into the death of a 10-year-old boy at Pirogov hospital in Sofia. His parents say doctors ignored him. The health ministry has also looked into the case.

The boy was hurt on 24 October in Etropole, when he fell from the ladder of a farm machine. He was taken to Sofia.
