By Allan Hall Suing: Dr Daniel Ubani is demanding 2,800 euros after a conference speech was disrupted A disgraced doctor who killed a British man due to an appalling blunder over his painkillers is suing the dead man's son in Germany because he missed a post-conference dinner. Rory Gray and his brother Stuart disrupted a speech he was giving at a conference on plastic surgery in the German town of Lindau in 2010, calling him a 'charlatan and killer'. Both men were arrested but later released. Dr Daniel Ubani is demanding 2,800 euros - plus legal and court costs - from Rory Gray who lives in Germany.
