The rescue service Air-Transport Europe says the crash occurred late yesterday near the village of Strelniky shortly after the rescuers took on board a man with a broken leg and the Bell 429 helicopter took off, heading to a hospital in the regional capital, Banska Bystrica.
Service spokeswoman Zuzana Hopjakova says it took several hours before the site of the crash was located early today in a local forest.
The victims were identified as pilot Jan Rusin, 50, doctor Patricia Krajnakova, 46, rescuer Frantisek Bartos, 32, and the 38-year old patient.
