    Jamaican police left stranded after thieves steal a beach This article is more than 17 years old

    Thieves in Jamaica have embarrassed police and triggered a political row by stealing a beach - and making a clean getaway.

    Hundreds of tonnes of white sand vanished from a planned resort on the island's north coast in July but three months later there is no sign of suspects nor sand.

    An estimated 500 truck-loads of sand were removed from the Coral Spring beach in Trelawny and were believed to have been sold to rival resorts, a hefty logistical feat which has stumped police.

    "It's a very complex investigation because it involves so many aspects," Mark Shields, the deputy commissioner for crime at the Jamaica Constabulary Force, told the BBC.

    Is it possible to just figure out the ratio of rocks and put them into a grinding machine to make custom sand?

      Zombocom… the only limit is your imagination.

      In all seriousness, rock crushing is energy intensive relative to just taking sand from the source.

        Create a bag of rocks and leave them in an area with lots of waves.

        Let nature and physics do the rest.

          Pretty sure this is a joke but you never quite know, given that HN is infamous for these "javascript programmer applies his smarts to something that's not javascript" moments.

            "bag of rocks" is so ridiculous that I would call it a joke for sure.

      Yes:

      The main problem is that even though crushing rocks is affordable, illegal sand mining is even cheaper in regions where law enforcement is weak.

      You'd also care about angular sand vs round sand grains.
