The force did not name the pair but they were named in press reports as Chief Inspector Sharon Rowe and Detective Chief Inspector Jim Torbet
Sussex Police issued a statement saying: “Two police officers have been suspended as a result of a criminal investigation. They have been bailed for further inquiries.”
Rowe is the force’s commander for the Worthing area while Torbet works in the force's professional standards department, responsible for overseeing officers’ conduct.
A letter has been sent to community leaders in Worthing informing them of a change of leadership in the town because Rowe would be absent "for the foreseeable future”.
