The Serious Fraud Office (SFO) and Essex police are looking into complaints made about the Harlequin group.
The SFO said: 'The business activity of the Harlequin group includes the marketing, sale and construction of luxury off-plan property developments in the Caribbean and other resort locations.'
'If you have invested in Harlequin schemes, we would welcome any information you can give us.'
The SFO said it was interested in hearing from people who invested in the following resorts
- Buccament Bay in St Vincent & the Grenadines
- Merricks in Barbados
- Marquis estate in St Lucia
- The Hideaway, Las Canas and Two Rivers resorts in the Dominican Republic
- Garapua beach resort in Brazil.
The SFO has issued a questionnaire for investors. 'Your answers will help us to understand the general nature of your evidence,' it said.
'We may then contact you to obtain a full witness statement for potential use in a criminal prosecution.'
Last week New Model Adviser® reported that the FSA had contacted Sipp providers to request information about holdings in Harlequin.
