A Derby taxi driver who was attacked and injured twice in three weeks is to pilot new CCTV technology in his cab.
Muhammed Ejaz Khan was beaten up when he refused to carry a fare, and robbed at knifepoint of his takings when two men guided him to a lonely dead-end.
Sgt Alec Wallace, from Derbyshire Police, said they were installing the video camera as a test case.
The initiative is part of Operation Relentless which is tackling violent crime.
The CCTV plan may be extended to other cabs in the city if it is deemed a success.
Mr Khan welcomed the police move saying: "I was really scared when I was attacked."
But he added he was still afraid to pick up somepassengers in the street.
The two-month Operation Relentless crackdown got under way on 1 May, with the intention of targeting key-crime areas including violence, anti-social behaviour, criminal damage, burglary and vehicle crime.
Police arrested 100 peole in the first week.
