Police are appealing for witnesses after a man was arrested on suspicion of attempted murder, following an alleged stabbing. Officers attended a call to an area of the A30 near Lewannick at around 7.30pm on Monday, June 2 and found a man in his twenties with a chest injury, believed to have been caused by a stab wound. He was airlifted to Derriford Hospital. His condition is described as stable and he has not suffered any life threatening or changing injuries. Following investigations a 50-year-old man from East Devon was arrested in Somerset on suspicion of attempted murder. He remains in police custody.
