A Sandall Park Angling Club member has managed to hook a mystery catch.
It is the first time this one has been caught and will give a nasty bite if handled wrongly.
SPAC Chairman Scott Holland said – “We’ve seen nothing like this before. It is possible that our new stock has had a reaction to the GM white bread and chapati that people feed ducks.”
A Friends of Sandall Park spokesman said: “For health and safety reasons it would be best to keep small children away from the lake”.
