Police are investigating the theft of a document containing allegations about new Humberside Police Chief Constable Justine Curran from her former workplace.
Specialist crime officers from Police Scotland have been brought in to investigate the theft of the document, which contained allegations about her conduct while she was in charge of Tayside Police.
The dossier was being kept in the executive corridor at the Tayside Division headquarters in Dundee. The corridor can only be accessed by staff with a security key.
A spokesman for Police Scotland said: "Police Scotland are conducting an inquiry into a theft from within Tayside division headquarters in Dundee. As this is an ongoing investigation, it would not be appropriate to comment further at this time."
The document details allegations of "unprofessional conduct" by Ms Curran, which led to two inquiries by the police authority. No action was taken.
A spokesman for Humberside Police said Ms Curran was aware of the matter.
