As per reports, two of his patients have been identified who had undergone a liver transplant under him and the doctor had made use of a laser beam to carve out his initials on the transplanted organ - a liver. 

The doctor has been identified as Simon Bramhall, who is accused of burning his initials "SB" onto the livers of two of his patients. Of the two patients while one is a man, the other is a woman. The doctor has admitted to two counts of assault but to the charge of causing bodily harm, he has pleaded 'not guilty'. 

How did the cases come to light? As per reports, the female patient faced some complications and the initials were discovered in a follow-up operation. 

The doctor is reported to have been a consultant surgeon at Birmingham's Queen Elizabeth hospital and reports have suggested that the doctor was asked to resign after the hospital initiated disciplinary proceedings against him in 2014.

What has also come to light is the fact that in January 2017, the General Medical Council had also issued a warning to him for failing to meet the requisite standards. In the present case, though the doctor has been granted an unconditional bail, the sentencing has been scheduled for 12th January.  

While his actions are undoubtedly unethical and criminal, but what is not clear is what motivated him to do so.
