Kent Police has launched an investigation into allegations of rigged roadside checks.
At least 120 speeding prosecutions have been dropped and an officer has been suspended in relation to the matter.
A spokeswoman told PistonHeads that the investigation is related to ‘the way in which speed camera equipment was used on a particular occasion’ but would not go into detail about where and when it happened.
The allegations surround how the equipment was used but Kent Police said it was ‘an operative issue’ and roadside checks could not be ‘fixed’ to show a higher speed.
The issue came to light following a court case that was discontinued.
The spokeswoman said: ‘This led to a member of staff being suspended for reasons connected with the case, which related to one specific occasion.
‘As a precaution, the decision was made to discontinue 120 prosecutions which were still pending at that time.
‘Our investigation into this matter continues.’
