Distressing new images have emerged today showing thousands of dead fish floating on the water in and around Salford Quays.
The Manchester Evening News first revealed the tragedy on Tuesday, with the Environment Agency confirming an investigation was underway.
A spokesman confirmed it has been dealing with multiple reports of 'fish in distress' and said it's believed to have been caused by 'a 'natural event caused by high temperatures and low atmospheric pressure as a result of thunderstorms, causing low dissolved oxygen levels'.
