Dylan says that he heard that the car owners had parked there after moving rocks deliberately placed on the field to stop people from accessing the land.
He also said that people need to ‘remember to be considerate’ and have some ‘common sense’ which he says ‘people sometimes forget’ when they are on holiday.
Dylan said that later the same day, he visited Ambleside and there were queues of cars waiting outside the local car wash.
Other people have posted online in support of the farmer.
One said: ‘Never mess with a farmer and never park in their fields.’
Another said: ‘If only there was a water shortage and the car wash had been shut.’
While a local said: ‘He should get a bonus from the carwash company.’
Another said: ‘This guy must be so frustrated, honestly. The absolute disrespect of some people.
‘If it was my field, I would do so much worse just for the audacity of ignoring my signs. He also needs that shit he’s wasting on these cars, so he’s actually at a double loss here.’
In a social media post, Cumbria Police said: ‘If you’re parking somewhere, make sure it is following the highway code and in an appropriate place that is not going to block any drivers – especially emergency services vehicles that may need to get through.’
A sign is visible which reads ‘Polite Notice – DO NOT PARK IN THE FIELD’ and above is another sign which says ‘SHEEP IN FIELD’
A spokesperson for Cumbria police said: ‘Police were made aware at 10pm on the 25 May of reports of cars having been sprayed with suspected cow slurry at a location near to Rydal.
‘Our Neighbourhood Policing Teams are carrying out further enquiries to determine the full circumstances.’
They also said it appears the cars had been parked on a farm owner’s land without permission.
The farmer, who is believed to have sprayed the slurry, has been approached for a comment.
