The Trust’s decision to return her job was described by Mrs Justice Yip as “surprising and extremely worrying”, as at that time she would have passed the compulsory retirement age.
He said: “Mrs Parveen was failed by both the Board and the doctor. There can be no doubt about that.”
Employers used to force workers to retire at age 65, but that law was dropped in April 2011, following an Age UK campaign.
Prosecutor Thomas told the court that Ms Parveen was with her husband Khizar Mahmood when she went to the biopsy and gave her consent for the hip bone sample to be taken from her.
After failing to use this “conventional” approach, Dr. Mamman decided to take a sample of the sternum.
This approach, although sometimes used, is extremely rare and is considered dangerous precisely because the heart is located directly below the sternum.
Thomas told the court that Mrs. Parveen lost consciousness as soon as the needle was inserted, but Dr. Mamman did not sound the alarm.
“I told him to stop three times”
A nurse said Mr. Mahmood ran out shouting, “He killed her. I told him to stop three times, but he didn’t hear me. He killed her.”
Speaking to another nurse, Mr Mahmood described in detail what had happened, saying: “[Dr Mamman] he continued to forcefully put the screwdriver inside his chest.
“There was blood everywhere, around his neck and on the sheets. This test has cost him his life.”
Thomas said the question of the doctor’s actual age was “a matter of controversy” as he does not have a birth certificate.
He was born in rural Nigeria who did not have a birth registration system.
He entered a medical university in Ibadan in 1958 and provided a date of birth on September 16, 1936.
He enrolled as a physician at the GMC in July 1965 and gave the same date of birth.
But at some point he claimed a later date of birth of 1941 when he obtained a Nigerian passport and that date was given to the businessmen.
‘He dedicated his life’ to patients
In 2001, he claimed an even later date in October 1947 in which he relied for his naturalization as a British citizen.
Thomas said that if this were true, he would have begun his medical studies at the age of ten.
Michael Hayton QC, in defense, said: “He is a doctor who has dedicated his life to the care and treatment of patients for many years …
“He should never have been able to carry out this procedure. His skills were considerably reduced compared to the younger doctor he was.”
Judge Yip said she would convict Mamman on Tuesday and told him she expected him to be sentenced to prison.
