The UK Border Agency said they had warned both Sutton and Surrey councils of their plans to shut down Carefirst 24, a nursing agency responsible for the care of elderly pensioner Gloria Foster.
Mrs Foster, in her 80s, was being looked after by the company and depended on staff for all of her medication, food and drink.
Six people were arrested following an investigation by the UK Border Agency and police into suspected assistance of illegal workers and fraud at Carefirst 24. A UK Border Agency spokesperson said:
Our thoughts are with Mrs Foster’s family at this difficult time.
We worked closely with Sutton and Surrey councils before the operation so they could put plans in place for anyone who would be affected by it.
