Police in Jamaica are investigating the suspected theft of hundreds of tons of sand from a beach on the island's north coast.
It was discovered in July that 500 truck-loads had been removed outside a planned resort at Coral Spring beach.
Detectives say people in the tourism sector could be suspects, because a good beach is seen as a valuable asset to hotels on the Caribbean island.
But a lack of arrests made since July have led to criticism of the police.
'Complex investigation'
The beach at Coral Springs, in Jamaica's northern parish of Trelawny, was 400 metres (1,300ft) of white sand. The 0.5-hectare strand was to form part a resort complex costing US$108m, but the theft of its most important feature has led to its developers putting their plans on hold.
Illegal sand mining is a problem in Jamaica; the tradition of people building their own homes here means there is a huge demand for the construction material. However, the large volume and the type of sand taken made suspicion point towards the hotel industry.
