Immigration arrests at Guy's and St Thomas' Hospital
Police have arrested 16 people working in Guy's and St Thomas' Hospital over alleged fraud and immigration offences.
The workers were arrested by the Metropolitan Police and UK Border Agency on Thursday.
A Met spokesman said the alleged fraud related to their employment at the hospital directly or through the Reed employment agency.
A spokeswoman for Reed said "sophisticated forged documentation" appeared to have been used.
She said: "Prior to the placement of these temporary workers, Reed had performed all checks legally required, but were misled by what appears to be sophisticated forged documentation.
"We are now working with the hospital to fill the vacant positions while these investigations are being conducted."
A Met spokesman said: "Sixteen people have been arrested in connection with immigration and fraud offences.
"Metropolitan Police and UK Border Agency officers carried out the arrests."
Guy's and St Thomas' Hospital said they would make a statement later on Friday.
