Yorkshire Water says it is investigating an unusual incident where bubbles filled a section of Hookstone Beck today.

Two Stray Ferret readers contacted us with photos of the beck this morning when what appeared to be a sea of washing-up liquid bubbles appeared on the surface.

Andrew Mann said he was out for a walk near the Yorkshire Event Centre when he noticed “something clearly had gone wrong”.

He said bubbles had risen 10-feet-high and raised concerns about any fish that might be swimming in the beck, which feeds into Crimple Beck.

A spokesman for Yorkshire Water said the incident was not related to sewage pollution. He suspected somebody had poured detergent down a drain that is intended for rainwater and runs off into the beck.

An investigation is underway to find the source of the problem and whether the substance is harmful to wildlife. Yorkshire Water will then share its findings with the Environment Agency.
