The full list of exemptions under the Act is shown below for your information. Where information falls within the scope of an 'absolute exemption', a public authority is not obliged to communicate it to an applicant. Information falling within the scope of a 'qualified exemption' must be assessed to decide whether the public interest in maintaining the exemption outweighs the public interest in disclosing the information.
If you require more detail it can be found in the The College of Policing's Authorised Professional Practice for the Freedom of Information Act.
