A tipper truck drove off at speed with its rear end still raised when it was spotted flytipping in Denbighshire.
A member of the public noticed the vehicle depositing a huge load of household waste at the entrance to a field between Eryrys and Graianrhyd, near Mold.
When the fly-tipper noticed they had been spotted, they drove off at speed with the rear of the truck still tilted.
But that meant that the member of the public was unable to spot the number plate.
Cllr Martyn Holland, in whose Llanarmon-yn-Ial ward the incident happened, said he believed repeated fly-tips were down to the same culprit.
Cllr Holland said: “Someone had backed into the gateway of a field on the road between Eryrys and Graianrhyd and tipped a large amount of household rubbish.
“The mess that has been left there stinks to high heaven, it seems to be general household waste including used nappies.
I’ve no idea why anyone would do this instead of using the normal bin collections or going to a recycling centre nearby.
In this area we are between three council areas that all have recycling centres quite close by.
“This is happening quite regularly around here and I believe that it’s the same people doing it because there have been reports of a similar lorry in the area when it happens.
“I hope people will keep an eye out and we can catch these people in the act and get their registration number.”
