NATURAL Resources Wales (NRW) confirmed it has dealt with a pollution incident in Pontithel.

Officers from NRW found around 200 dead bullhead fish in a seven-metre stretch of the Llynfi River.

They have now launched an investigation to find out what caused the pollution.

A spokesman posted on the NRW Twitter page: “The pollution has stopped and no further fish deaths have been seen.

“Our officers are gathering evidence and taking water samples. The investigation is still ongoing.”
