EMPLOYEES at ITV testing centres have been arrested as part of an investigation into the alleged falsification of Harley-Davidson paperwork.

It is claimed that mechanics and other workers altered the documents of imported motorbikes to meet European regulations.

The bikes affected are believed to have been imported directly from the US by their owners rather than through official Harley-Davidson dealers in Spain.

Suspicions were raised earlier this year after an unusually high number of the famous bikes were being submitted for the ITV test at a centre in Cuenca.

A subsequent police crackdown has seen many riders having their driving licenses confiscated and their bike taken off the road.
