German police caught two thieves breaking open "lovers' padlocks" attached to a bridge over the Rhine River in the city of Cologne.The pair were cutting padlocks, left by amorous couples to symbolise their eternal love, off a railing on the Hohenzollern Bridge presumably to sell as scrap metal, police said."I spotted two men on the other side of the bridge tampering with the lovers' padlocks, so I called for back-up straight away," a police officer said. The men tried to escape with their loot after spotting police but were apprehended on the bridge.Police discovered over 50 padlocks along with lock cutters in a trolley suitcase, wheeled along by the men. The pair will appear in court on charges of property damage, police said.Love-struck couples have been fastening padlocks to railings of bridges, engraving them with their initials or adding a few sentimental words and then tossing the keys into the rivers below to symbolise their eternal love.
