Tayside Police officers to be questioned in drug squad probe
Members of Tayside Police's drugs squad are to be questioned as part of an investigation into the way detectives obtain information.
Twenty-four officers have been told to make themselves available for interview by Grampian Police, who have been brought in to conduct the inquiry.
None of the officers have yet been questioned.
The probe, which is being directed by the Crown Office, began after an internal Tayside Police inquiry.
The investigation into the methods used by detectives to obtain information was launched at the beginning of the year.
BBC Scotland understands not all of the officers who are to be questioned are members of the Tayside Drugs Squad, but may have been working as part of wider campaigns.
The secretary of Tayside Police Federation, David Hamilton, said the officers involved were happy to assist the investigation, and were keen for the situation to be resolved.
A Tayside Police spokesman said: "Tayside Police identified matters of concern about the working practices of certain individuals and, following discussions with the procurator fiscal, it was requested that Grampian Police conduct an independent investigation into the full circumstances.
"To date a number of police officers have spoken with the investigation and officers will continue to assist the inquiry team as required.
"It is not appropriate to comment further at this time."
A Crown Office spokesman said: "We can confirm that the senior procurator fiscal in Tayside has received information relating to alleged incidents involving serving police officers.
"These matters remain under consideration and it would not be appropriate to comment further at this stage."
