Prosecutor-General spokesperson Rumyana Arnaudova has announced that the Prosecutor's Office is launching an investigation over dereliction of duty in the Pirogov emergency hospital and six other hospitals across Bulgaria.

The spokesperson recalled that two other hospitals have been under investigation, too. Cases concern the so-called “hospital in hospital” model, in which state-owned or municipal medical establishments allow private hospitals to operate in their buildings, as the practice has been banned since 2010.
