AN overseas locum doctor who administered a fatal dose of diamorphine to a 70-year-old man suffering from kidney stones was reading a medical manual on the day of the death, an inquest heard today.

Daniel Ubani, 66, from Germany, was working his first shift for Take Care Now, an out-of-hours care provider, when he injected David Gray with 100mg of the drug - ten times the recommended daily dose, Mr Gray's family's solicitors have said.

Take Care Now provided out of hours care for Suffolk and Cambridgeshire until recently.

The inquest heard how on the day of Mr Gray's death Dr Ubani was flipping through a manual called the British National Formulary.

A spokesman for Anthony Collins Solicitors, which is representing the family, said that Mr Gray died after receiving the fatal dose at his home in Manea, Cambridgeshire, on February 16, 2008.
