Donegal County Council has confirmed it has discovered a large illegal dump in Inishowen.
The discovery was made earlier this month near Burnfoot following monitoring of the site by council investigators.
It is understood council staff found a lorry and its driver on the site when they raided it.
The dump is the first sizeable illegal dump to be found in the county for several years and it is believed it could contain several hundred tonnes of waste.
Donegal County Council said it could not comment on the case as it may be subject to legal proceedings.
