A New Forest cycle race was disrupted after tacks were placed along the race course to puncture tyres.
Cyclists who took part in the Wiggle New Forest Spring Sportive race suffered punctures at the event on Saturday.
Hampshire Police conducted house-to-house inquiries in the village of Bransgore after 15 cyclists suffered punctures.
This is the second time the race has been targeted and it came after posters were put up locally warning of the 'abuse of our tranquil locality' caused by the 2000 competitors.
It was surprising and disappointing to see a handful of anti-cycling campaigners trying to disrupt the event again this year by throwing tacks on to the road on several occasions. Our support teams, however, cleared these away before they could harm the riders, local drivers and New Forest animals."
