A FORMER ESSEX police chief constable faces legal action over Â£85,000 of so-called "retention payments".
Essex Police and Crime Commissioner Nick Alston said he had begun legal proceedings against Roger Baker to recover the money, plus interest.
Mr Baker, who later took a job as a non-executive director at Colchester Hospital, has declined to comment.
He retired from his position with the police force in 2009, after almost four years in the role.
Mr Alston said: "In the summer of 2013, I was advised that so-called ‘retention payments’ made to Roger Baker, a former chief constable of Essex Police, were outside the national Police Negotiating Board agreements.

"Since that time, I have been seeking clarification of the rationale and legal authority for those payments."
He also said he had called for a national review of chief officer allowances and bonuses to "guarantee consistency and accountability".
