A police commander has been suspended over allegations of gross misconduct.
Milton Keynes police boss Supt Gez Chiariello is alleged to have breached standards in relation to authority, respect and courtesy.
The 46-year-old joined Thames Valley Police in 2007 and became the town's area commander in 2014. He has been suspended from duty with immediate effect.
Acting Supt Vince Grey has been appointed to fill his role.
A date is yet to be scheduled for the misconduct hearing.
Deputy Chief Constable John Campbell said: "Thames Valley Police's professional standards department is currently investigating allegations of misconduct into Supt Gez Chiariello.
"The facts will be heard by a panel, chaired by a legally qualified independent chairperson, who will determine if there is a case to answer for gross misconduct and if there is, the appropriate sanction to be applied."
