More details about the council employing illegal immigrants have been revealed after two more people admitted using false documents to trick the authority into employing them.

One of them used a fake name while he was employed.

Last week the Free Press revealed how two women used fake identification documents and a bogus Home Office letter to dupe the authority into employing them as cleaners for several years.

The pair earned over £40,000 between them before they were arrested by immigration officials.

Now its has been revealed that at least ten people were arrested during a series of raids in Doncaster which led to the convictions of Prisilla Sarpon and Maria Chisadza.

Jules Kepseu, also known as Guy Romford, and Emma Ceasar, both illegal immigrants, have pleaded guilty to obtaining a pecuniary advantage by deception and using a false instrument.

Paul O'Shea, prosecuting, told Ceasar's hearing at Doncaster Crown Court: "At the same time this lady was arrested it was part of a wider operation in the Doncaster area of those people employed by Doncaster Metropolitan Borough Council in their cleaning system. There were ten of them."

Ceasar, of Furnivall Road, Balby, will be sentenced this month.

Kepseu, 38, of Axholme Road, Wheatley, was jailed for 18 months after using a fake Belgian passport to trick the council into employing him shortly after his arrival in the UK in June 2005.

He earned over £10,000 as a cleaner before his arrest in March.

Michael Rawlinson, defending, said Kepseu fled Cameroon as he was repeatedly arrested and tortured for being a member of a political party his father was murdered for representing.

Kepseu, a university graduate, had left his wife and one-week old child, and was working 13 hours days, often seven days a week to send money back to his family.

He was also working to pay off £1,200 he owed to a Congolese gang who had sold him the passport in Belgium and who had threatened his mother, Mr Rawlinson added.

The court was also told Kepseu was paying National Insurance and intended to move his family to the UK and claim asylum.

Kepseu was sentenced to 18 months for each offence to run concurrently. He will be recommended for deportation on his release.

Judge Rodney Jameson QC said: "He appears to have worked hard for his money but he earned money he was not entitled to at the expense of someone else who was entitled to.

"It is common knowledge that the passport system is subject to abuse."

After the hearing, Doncaster Council confirmed Ceasar, was contracted to work 30 hours a week for at £6 an hour.
