Police in Cambridgeshire are asking for more Government money to cope with problems caused by a flood of migrant workers. The Chief Constable says ministers have been short-changing the county for years, ignoring the costs involved in policing a growing population of non-English speakers. Figures released today show rises in prostitution, knife crime and drink driving. When dealing with those crimes, officers have to work in 90 different languages and pay more than 8-hundred thousand pounds a year in translation bills.
