A chief constable who highlighted the policing problems caused by immigration from eastern Europe is standing by her remarks.
Julie Spence, head of Cambridgeshire Police, said immigrants were not responsible for a "crimewave" but recent population growth had given police "significant challenges".
She was speaking after a new police report suggested that immigration sparked by the widening of the European Union had not caused a rise in crime.
"The growth in our population has brought about significant policing challenges, not least the amount of time and effort we put into dealing with offenders whose first language is not English," said Mrs Spence.
"Similarly, looking after victims and witnesses and managing community tensions is substantially more complex now than three years ago.
"We currently deal with people from 93 different cultures speaking more than 100 different languages, which in itself highlights the challenges we face.
"We have seen an increase in specific offences such as motoring offences, sex trafficking, and worker exploitation - a form of modern day slavery.
"Our workload and its complexity is increasing.
"Some parts of the country are no doubt unaffected by this. However, Cambridgeshire certainly is."
