GP 'disguised himself to kill mum's partner with home-made ricin'

He 'posed as nurse to give jab over will row'

- JEREMY ARMSTRONG

A GP disguised himself as a nurse and injected his mum's partner with poison in a plot to kill him for her inheritance, a court heard.

Thomas Kwan, 53, became obsessed with ricin, arsenic, cyanide, and nerve agents and pretended he was giving Patrick O'Hara, 71, a Covid booster jab on a home visit.

The poison he used on January 22 was believed to be iodomethane, a pesticide, which had never been administered to a human before, Newcastle crown court heard.

After his arrest on February 5, officers found ricin, castor beans and guides on making it at his home, the jury heard.

Kwan used the surgery he worked at in Sunderland and a fake research firm as fronts to buy dangerous chemicals, said Peter Makepeace KC, prosecuting.
