The number of sick days taken by Gloucester Police force due to stress rose last year to more than 4,000, a Freedom of Information request has revealed.
The request by the BBC found that in total there were 4,254 days when officers were absent due to stress last year.
The number of days lost to stress rose to 4,254 in 2011/12, an increase from 2,586 in the previous year.
Gloucestershire’s Assistant Chief Constable said she was “concerned” by the findings.
The statistics were released under the Freedom of Information (FOI) Act, following a request by the BBC.
The average length of time officers were off sick also increased to 55 days from 45 days the year before, the figures show.
Assistant Chief Constable Sally Crook said: “Of course we are concerned about the increase but the figures are complex.
