Doncaster has four prisons and incidents in and around those establishments has historically created a significant draw on police resources, with officers needed to respond to crimes within and around the prisons.
As a result a new team of officers was set up in January to work with prison managements and staff, with the intention of reducing crimes and investigating those which occur more effectively.
The project has had a positive impact, with criminal incident levels as high as 109 for August last year across the four prisons down to 26 in June and 28 in July.
Details of the success were provided in a report to South Yorkshire Police and Crime Commissioner Dr Alan Billings.

The new Prison Crime Unit has six police officers and eight investigation officers, who work alongside prison staff.
The report stated: “The improved relationship and processes have led to speedier justice and a notable change in offending behaviour within the prisons.”
