The trial is taking place at the High Court in Livingston. A KELTY dad who repeatedly stabbed another man with a potato peeler was acting in self defence, a jury has been told. Campbell Gray, 31, of Blair Street, is charged with attempting to murder Martin Davie on March 27 last year and attempting to defeat the ends of justice by dumping the kitchen implement in a street drain. The prosecution and defence have jointly agreed evidence that he was responsible for stabbing Mr Davie three times to the right side of the chest, severing an artery and putting his life in danger.
