The Police Investigation & Review Commissioner (PIRC) is investigating allegations against a number of officers working for Police Scotland.
Investigations have begun in relation to how officers dealt with the alleged wrongful arrest of a man in April 2015.
A spokesman for the PIRC said: “PIRC is undertaking an investigation into allegations of criminal neglect of duty against a number of officers serving with Police Scotland.
“The potential criminality was identified by the Commissioner while conducting a Complaint Handling Review (CHR) into how Police Scotland dealt with complaints relating to the alleged wrongful arrest of a man in April 2015.
“The matter was drawn to the attention of the Crown Office and Procurator Fiscal Service (COPFS), who have now referred it to the PIRC for investigation.”
