A drug dealer has been found guilty of stabbing a police officer in an attack that left his victim with a collapsed lung. Michael Enzanga was likened to a "caged animal fighting for his life" as he repeatedly knifed Hampshire Police Constable Russell Turner, 56, on February 21 at Stamshaw Park in Portsmouth. Pc Turner had been looking into reports of drug dealing in the area with colleague Pc Claire Parry. Both officers were in plain clothes at the time. A jury at Portsmouth Crown Court took one hour on Thursday to find Enzanga, 20, of Ashfield Road in Tottenham, north London, guilty of causing grievous bodily harm with intent and possession of a knife. He was also convicted of four charges of possessing crack cocaine and diamorphine, with intent to supply the class A drugs on February 20 and 21, and a charge of possessing criminal property, namely a stash of money.
