LONDON — Proving the adage that no good deed goes unpunished: British police say a doctor's car was stolen after she rushed out to help an elderly crash victim.

According to police, the doctor left her car key in the ignition when she hurried to the aid of a pedestrian who was hit by a bus in the English city of Manchester.

As she was tending to the man's wounds someone jumped into her car and drove off. Police did not identify the doctor or the male victim, but said he appeared to be in his 70s and had suffered head injuries.

Inspector John Kelly said the doctor's compassion was "totally taken advantage of by a pathetic opportunistic thief."

Greater Manchester Police said the pedestrian was hospitalized Wednesday in critical condition. Manchester is about 200 miles north of London.
