Four arrested over 'sham marriage' in Oxford
Four people have been arrested in connection with a suspected sham marriage in Oxfordshire.
It follows an undercover operation by officers from Thames Valley Police and the UK Border Agency.
Three Polish nationals and an Indian national were arrested while preparing for a wedding ceremony at Oxford Register Office.
Two addresses in the city were also raided in connection with the investigation.
The UK Border Agency has seen a slight increase in the number of sham marriages across the country.
The Agency suggests factors such as the tightening of immigration controls, the current economic climate and efforts to make illegal working more difficult have all contributed to the rise.
Terry Gibbs, from the UK Border Agency, said: "The UK Border Agency is committed to striking at the heart of illegal immigration and taking those who attempt to break the rules and if we suspect a marriage is not genuine we will take action."
