More than 30 Northamptonshire Police staff are to be transferred into the private sector, the Chronicle & Echo has learnt.
The force is planning to transfer 32 staff, who work in the Criminal Justice Centre in Northampton, to the employment of G4S, a security services company.
We are currently working with G4S to deliver detention officer services in the county.
No jobs will be lost as a result of the changes, which are set to be introduced by May 1.
A spokesman for Northamptonshire Police said: “We are currently working with G4S to deliver detention officer services in the county.
“The move would result in 32 positions being transferred from Northamptonshire Police to G4S. Staff have been fully consulted about the proposed changes and there is no plan for any jobs to be lost as a result of the move.”
A Northamptonshire Police employee, who did not wish to be named, said staff involved were worried that it was “privatisation of the police force through the back door”.
The use of private contractors to run backroom police services has been carried out in other parts of the country.
G4S entered into a £200m, 10-year contract with Lincolnshire Police in 2012, with 550 civilian staff transferring to the company.
Police and Crime Commissioner (PCC) Alan Hardwick said the changes had saved the force £5 million in its first year.
However critics of the move said it was too early to tell whether G4S had managed to save the police force a significant amount of money.
