A car thief called Duncan Fagg was caught after leaving his DNA – on a CIGARETTE BUTT.
Fagg, 36, crashed a nicked Nissan Micra and fled the scene but left the dog-end behind.
Police matched his DNA and Fagg, of Rochester, Kent, admitted a string of offences.
He was jailed for 18 months and disqualified from driving for three years at Maidstone Crown Court.
