AN out-of-hours doctor who killed a pensioner with a painkiller overdose has been struck of the medical register.

Dr Daniel Ubani flew into the UK from Germany and injected David Gray, 70, with 100mg of a pain relief drug - 10 times the recommended dosage,

Mr Gray died at his home in Manea, Cambrideshire, a few hours after he was given the massive overdose of diamorphine on February 16, 2008.

Ubani was working at the time for the then Suffolk-based out-of-hours provider Take Care Now, which have since been replaced by Harmoni.

A General Medical Council Fitness to Practice Panel concluded it had “grave concerns” about Dr Ubani’s clinical competence in his treatment of three patients on that date and warned there was a risk of him repeating his errors.
