When two teenage boys went fishing from a river bank in Oxford, they didn't set out to catch a rifle.
But when Alex Weller and Josh Cooks fishing line snagged on a briefcase, they hauled it ashore and found exactly that.
The briefcase contained a rifle, a pistol and ammunition which has been described as a typical hit man's gun kit.
Detectives are now investigating whether the high-powered gun could be linked to a major crime.
