Thirteen police officers in Northampton are to go back to school to learn to speak Polish.
The officers from the Northamptonshire West police area will attend Polish language and culture sessions at Campion School in Northampton.
The weekly lesson at the Language College in Kislingbury Road, Bugbrooke, will last one-and-a-half-hours and will run for up to 10 weeks from 2 October.
There has been an increase in the number of Poles living in the county.
Insp Chris Hillery, of the Northamptonshire West Police Area, said: "We have got an increasing population of Polish nationals and speakers in the county.
"A number of them have been victims of crime and this will help to allow us to build trust and confidence with members of that community.
"The courses will also give the officers an understanding of Polish culture."
