Police in Queensland will this week be asked to launch a murder investigation into claims a doctor killed patients.
Former independent Queensland MP Rob Messenger gave taped interviews of a former colleague of the doctor to media and the Crime and Misconduct Commission (CMC).
On the tape, the whistleblower doctor accuses his former colleague of at least two killings.
One of the incidents involved oxygen being turned down on a patient on life support, which prematurely killed the woman against her wishes.
On another occasion, a surgeon had to restrain the doctor for 15 minutes to stop him from hurting a patient.
"He was prepared to kill people if it saved his authority from being questioned," the doctor said in the recording.
Health Minister Lawrence Springborg said that the doctor was still employed by Queensland Health but had been separated from patients.
