Police chiefs in South Yorkshire have bought the land to build a new custody suite on.
The deal for the land on Shepcote Lane, Tinsley, has gone through this week, after Sheffield City Council granted planning permission for the purpose-built custody suite last month.
Work on the new 50-cell suite, which will replace existing aging facilities in Ecclesfield, Sheffield city centre and Rotherham, is due to begin next month.
The force wants the complex to be used by partner agencies involved in investigations into crimes to provide a more joined up system.
Chief Superintendent Rob Odell said: “The force has to make significant savings from its total budget but at the same time we need a workforce properly equipped to tackle crime and protect the public.
“Creating modern, more cost effective custody suites is just one part of this process and given the size and scale of the proposed sites, we expect the overall budget will be in the region of £19 million.
“We anticipate that replacing three existing properties within Rotherham and Sheffield with one purpose-built facility will deliver annual savings of approximately £1.2 million. The majority of this will come from a reduction in staffing.
“We are consulting with the staff affected and we hope to achieve the savings through natural wastage.
“Our custody staff have one of the most challenging roles policing South Yorkshire and I’m proud of their professionalism in dealing with some of our most difficult customers.
“Providing an integrated, modern custody building will give those staff a better working environment in which to manage high-risk situations and will help us to return officers to the streets at the earliest possible opportunity.”
