Cayman NetNews has reported that:

The Governor of the Cayman Islands, His Excellency Stuart Jack, CVO, today (Thursday, 27 March) announced that he has put three senior police officers on required leave to facilitate enquiries into allegations against officers of the Royal Cayman Islands Police Service (RCIPS).

Police Commissioner Stuart Kernohan, Deputy Commissioner Rudolph Dixon and Detective Chief Superintendent John Jones were put on required leave with immediate effect to enable an investigating team from the Metropolitan Police Service led by DCS Martin Bridger to proceed with their enquiries.

As Cayman NetNews rightly says, there must be a presumption of innocence at this stage. It's interesting to note the follwoing though:

In a separate statement, Senior Investigating Officer Martin Bridger said that much of his 30 year career as a detective has been spent dealing with issues of integrity within the police services. This included working in the Anti-Corruption Unit of London's Metropolitan Police Service, Northern Ireland's Police Ombudsman Office and advising other UK and European police services on how to meet the challenges offered by breaches of integrity and wrongdoing.

I think the nature of the allegations are clear.
