Chilling moment GP who tried to kill stepdad with poisoned jab is arrested in his pyjamas

This is the moment a GP who his stepdad by poisoning him with a fake Covid jab is arrested in his pyjamas.

Thomas Kwan was today jailed for 31 years and five months for trying to to kill Patrick O'Hara, now 72, after experimenting with a series of noxious substances, including castor beans to make ricin, in a row over his mother Jenny's will.

Kwan, 53, dramatically changed his plea to guilty mid-way through a trial at t earlier this month. Mr O'Hara was rushed to hospital in the weeks after the jab, diagnosed with necrotising fasciitis, a life-threatening flesh-eating disease, and had to be treated in intensive care.

In footage released today, Kwan is seen in his home being arrested by an officer while standing in his pyjamas. In the clip, he doesn't appear to say anything but acknowledges that he understands why he has been arrested.

Mrs Justice Lambert today told Kwan: "Your intention of visiting the home was to administer a lethal injection of poison to Mr O'Hara on the pretence of administering a Covid booster. It was an audacious plan to murder a man in plain sight and you very nearly succeeded in your objection.

"You were in the home of Mr O'Hara for 40 minutes and for some part of that your mother was also present and you took her . Extraordinary though it seems, so trusting were they that neither recognised you under your disguise."

Justice Lambert said financial gain was the motive behind the attempted killing and added: "You were certainly obsessed by money and more particularly by money which you considered yourself to be entitled.

"I have no doubt that the reason why you tried to kill Mr O'Hara was for financial gain. You knew your mother had left the house to her children but you also knew she had changed her will to give Mr O'Hara a life interest in the house. By killing him you removed the obstacle which lay between you and your recovery of your share of the property following your mother's death."

During the trial, the jury was shown the opening shot of a video of Mr O'Hara in the ICU unit of the Royal Victoria Infirmary, close to the home which he shared Jenny, 73, in which he gave an account of the poisoning. The full interview could not be played in court due to a technical issue. But there was a noticeable change in the demeanour of Kwan when he returned to court afterwards, as he sat with his head bowed before the jury was sent home. The video interview was due to be played in full to the jury the next day, but Kwan opted to plead guilty.

Mr O'Hara, who said the attack should have been the "end of me", spent five weeks in hospital, faces ongoing treatment and has been to "hell and back". The former environmental analyst said he has always been healthy and when he received a letter he thought was from the about a home visit to administer the jab he did not suspect anything untoward.

But he added his life "completely changed forever" when the needle went in: ""The doctors at the RVI informed me that I had had been diagnosed with necrotising fasciitis and that my body was suffering from a 'flesh eating' disease. In order to cure this disease, I underwent three separate operations, which required surgeons to cut away large parts of my left arm to ensure that all the signs of the disease had been removed so that it wouldn't continue to spread."

He added: "There was never a day that went past when I did not feel pain." Mr O'Hara, who said he "didn't want to believe it" when he found out the truth of what had happened, said his health has continued to suffer He added: "I will never get over the anxiety and pain that he has caused me and my family."

Kwan refused to assist police when his stepdad, a retired environmental analyst, went into intensive care with rare bacterial bug Necrotitis Fasciitis, a flesh eating bug, caused by his injection.

Officers found a host of poisons and noxious substances at Kwan's address, including the ingredients for the chemical weapon ricin. But he would not tell them which one he had used.

They discovered he had set up his own firm, pretending to be a research chemist, in order to source the poisons, or the chemicals used to produce them.

In the end, the poison in the fake jab was identified as the fumigant pesticide iodomethane, never seen before in a human, by a MoD expert. It left horrific injuries, with the prosecution producing a series of images of the damage to Mr O'Hara's arm, neck, chest and back.

The impact of the poison was so severe that surgeons had to cut away the skin on his left bicep and shoulder, exposing the muscle, to save his life.
