A stunned magnet fisherman hauled out two hand grenades from a Fenland drain.
He was dangling his line in the North Level Drain at Tydd St Giles, near Wisbech, when he made the explosive find.
Police sealed off the B1165 at Church Lane Bridge and called in bomb disposal on Monday night.
They later tweeted: “Officers set up a 100m cordon and the B1165 Church Lane bridge was closed while the grenades were safely removed from the area by the Explosive Ordnance Disposal (EOD) team.”
It is not clear how the grenades ended up in the drain. In May, a First World War bomb was found on the banks of the drain under the A1101 bridge at Tydd Gote.
It was destroyed by experts in a controlled explosion. It was believed to have been brought to the surface by a magnet fisherman.
