ENVIRONMENT officers have visited the Pembrokeshire home of television presenter and comedian Griff Rhys Jones, after dead fish were found in the stream and the millpond.

The entertainer, whose restoration of Trehilyn Farm was documented in BBC Two's A Pembrokeshire Farm, returned to the remote spot, near Trefasser, earlier this month to find dead sea trout and eels, which are a protected species.

Posting pictures on Instagram the star wrote:

"We arrived at Trehylin to find our water poisoned. The stream that runs through our land has been badly polluted. All the little trout in the mill pond near Bwthyn have died. These small eels were dead at the ford.

"It is part of a nature corridor, and the devastation will have spread right downstream. The clear water that has sustained a huge variety of wildlife has died."

Mr Rhys-Jones added that the pollution seemed to have been caused by 'careless slurry dumping upstream'.

He added: "This is happening across the United Kingdom."

Robert Philips, environment team leader for Natural Resources Wales confirmed that an investigation into the issue was taking place.

"Last week our environment officers attended a site at Trehylin in Pembrokeshire, following reports that a number of dead fish were found in a local water course," he said.

"Our investigation is ongoing."

Anyone who has any concerns regarding pollution can report them to NRW via the Incident hotline on 0300 065 3000 which is open 24/7 or by using the online incident form.
