A blood bank boss has been arrested amid claims she sold blood to wealthy customers, while refusing it to poor people and those she suspected of being gypsies.
Detectives tapped the phone oft Dr Cristiana Maria Stoian, the director of a public transfusion centre in southern Romania.
It is alleged they overheard the doctor refuse to give a 13-year-old girl blood because she was a gypsy.
Police have confirmed the doctor had been taken into custody on allegations of abuse of trust, blackmail and bribery.
They are also investigating the death of seven patients, who may have died as a result of the doctor either refusing to give them blood for transfusion, or alternatively not giving them enough blood.
Transcripts of the phone conversations were recently made public in Romania.
It includes a conversation in October last year, in which she is told by a nurse that a 20-year-old female patient who had just given birth urgently needed blood if she was to survive.
The doctor is said to have replied: “Goodbye then, let her family know.”
