West Mercia Police could face a further £20 million in cuts
Police staff in Shropshire could face cuts as part of cost-cutting measures to save a further £20 million.
West Mercia Police and Warwickshire Police have almost finished a three-year plan to shed £30 million.
It started in 2012 and included the loss of 140 front line police constable jobs.
But a new plan to save a fresh £30 million between the two forces must now be drawn up, starting next spring and running until April 2018.
It is not known how cuts, which could be from administration, finance and operational support roles, would impact front line officers.
The total saving is expected to be divided approximately with £20 million from West Mercia Police and £10 million from Warwickshire Police.
Superintendent Gary Watson, from West Mercia Police, said: "This is a saving that is facing police across the whole public sector. It's too early for us to provide any real detail. Clearly protecting the front line will be a key part of what we need to do but, as with all organisations, the front line can't operate without support functions assisting it."
The forces revealed in 2012, 650 jobs would be lost. The announcement said staff would be reduced from 5,400 to 4,750 by April 2016, with the number of Pcs being cut from 2,300 to 2,210.
West Mercia Police is also in the process of closing 33 police stations and buildings to save £1.5 million. It was reported in January this year that West Mercia Police needed to make a further £22 million of cuts by 2019.
It embarked on an alliance with Warwickshire Police to help reach its savings target.
Several police stations around the county have also been closed as part of the cutbacks, including in Ellesmere and Newport.
The current West Mercia Police budget is around £203 million. Firm proposals and more details on cuts will become clear in the coming months.
