A doctor who botched a routine procedure that killed a mother of three was sentenced to jail.
Now thought to be 85 years old, Dr Isyaka Mamman admitted gross negligence manslaughter in the 2018 death of Shahida Parveen at the Royal Oldham Hospital.
He used the wrong needle, and inserted it at the wrong location. This caused Mrs Parveen to lose her heart.
Manchester Crown Court Mrs Justice Yip ruled that Mrs Parveen's suicide was his fault, and sentenced him for three years.
She also criticised NHS trust, pointing out that Mamman had both lied to his age and been involved in two similar incidents to that which caused Mrs Parveen to die.
The court was informed that Mrs Parveen visited Royal Oldham Hospital on September 3, 2018, to take a sample of bone marrow.
This is normally taken from the hip bone, but Mamman failed to succeed in his first attempt and decided to take it from Mamman's sternum.
The court was informed that this was a dangerous procedure and had resulted in another Mamman patient being permanently disabled three year prior.
After a patient complained that Mamman used excessive force during a bone-marrow biopsy, a formal complaint was filed against the hospital.
Unnamed patients were told Mamman was "in the 70s" and that his colleagues believed he should retire. However, they couldn't dismiss him simply because he was his age.
He was to be assigned light duties in the future, she was assured.
The court heard that Mrs Parveen became unconscious as soon as she was needled and that the needle pierced her pericardium (also known as the heart sac), causing extensive internal bleeding.
Her husband ran out of the room screaming: "He killed his wife." He didn't listen when I asked him three times to stop. He murdered her."
Haemotologist Mamman was a Nigerian doctor who had been working in the UK since 1991.
From 2004 to Mrs Parveen's passing, he was employed at Pennine Acute Hospitals NHS Trust.
Mamman's "true ages" are a matter of "controversy", according to the court, as his birthplace in rural Nigeria did not have a system for birth registration.
He stated that he was born 16 September 1936. This meant that he was 21 years old when he started his training to become a doctor. He was also qualified in 1965 and was 81 at his death.
He also revealed to NHS bosses that his birth year was 1941, suggesting that he began his medical education at the age of 16.
In 2001, as he approached the mandatory retirement age of 65, his birth date was October 1947. He applied for naturalization to Britain.
This would have meant that he was only 10 years old when he began his medical degree.
In 2004, Mamman was found guilty by the General Medical Council of serious professional misconduct (GMC) and was suspended for 12 month for lying about his age.
After he was restored to the GMC's register, the Pennine Trust fired him. However, they rehired his services in 2006.
This would indicate that he was only 14-15 years old when he started his training.
Mamman did not react to his sentence, but family members wept in public gallery.
Mrs Justice Yip stated that it was difficult to understand why Mamman had not retired from medicine due to previous serious incidents and added that there had been "failings within the system."
Dr Chris Brookes is the deputy chief executive of the Northern Care Alliance NHS Foundation Trust. He said that "we wish to send our deepest condolences to Mrs Parveen and her family and friends, and we are deeply sorry for their loss."
He stated that the trust had admitted to liability for a civil lawsuit brought by the family.
