The "theft" of a three-storey, seven-tonne mango statue in northern Australia was revealed on Tuesday to be an elaborate publicity stunt by a fast-food chain. Monday's disappearance of the Big Mango, a towering fibreglass likeness of the fruit which is abundant in its hometown of Bowen, made international headlines and a Facebook page was set up to help find it. But a chicken restaurant chain has said it was responsible for "borrowing" the tourist attraction. "The disappearance of Bowen's Big Mango has generated quite a lot of attention over the last day or so, and we confess Nando's was behind moving the three storey high, ten tonne tourist attraction," it said on its website.
