A spokesman for Cambridgeshire Constabulary said: “If a person magnet fishing uncovers what they believe may be an explosive device they should dial 999 immediately and inform police.” The Environment Agency does not regulate magnet fishing in Cambridgeshire. The growing practice is not illegal but the advice is anyone wishing to go magnet fishing should obtain permission from the land owner, as well as the owner of any fishing rights. However a number of high-profile incidents have led to magnet fishing being branded as unsafe, following the death of two men from Leeds who drowned while trawling a bottom of a canal in Huddersfield. Martin Andrews, 43, and his son Jack, 19, used a powerful magnet to “catch” pieces of metal , but ended up being pulled into the water in June. Another incidents that made the national news, have included unexploded World War II bomb was fished in Northamptonshire in June. And in November a woman magnet fishing in Wales pulled an unexploded World War II shell from a canal. All such incidents require the employment of bomb disposal squads and pose a public risk.
