As well as two money-transferring businesses and bank accounts, investigators also discovered Mayomi owned a fish farm in the country.
The couple’s benefit scam unravelled when a visa application by Mayomi showed they had married a year earlier and that Ubiribo had a job in order to support him.

Ubiribo also asked the council to rehouse her because she was the victim of domestic violence.
However, the telephone number she gave revealed the man she named as her landlord – Ayiomike Neburagho – was, in fact, her husband Mayomi using a false identity.
At a police interview, Mayomi admitted that while living in Nigeria he had bought the identity of Ayiomike Matthew Neburagho and had entered the UK as him.
Mayomi was also shown a wedding photograph of himself, using the Neburagho identity, marrying a Nigerian woman in the UK.
He admitted he was the groom in the wedding photo but he said he was ‘just standing in for someone’.
Ubiribo and Mayomi pleaded guilty to all charges.
Mayomi was jailed for 30 months two years ago and his wife was sentenced to 12 months in prison, suspended for two years.
She was also ordered to carry out 200 hours of community service and be under curfew for four months from 9pm to 6am.
Court orders were signed freezing their assets in the UK and abroad in 2010, and an investigation was launched to find out how much the Nigerian-born couple had gained from their criminal lifestyle and what the extent of their assets was.
Mayomi, of Ashburton, disputed the results of the assets investigation, and a subsequent four-day confiscation hearing took place at Croydon Crown Court.

On Friday, Judge Nicholas Ainley ruled that Mayomi must pay £1,197,743.54 by 14 March next year. It is one of the largest confiscation orders carried out by a council.
Failure to do so will see him sent to prison for six years, during which time interest will accumulate on his debt, which will remain due following his release.
At a hearing in July, a confiscation order was made against Ubiribo for £9,357.42 to be paid by 19 October or face five months in prison.
Investigators had discovered she was the owner of a Rolex watch and a Mercedes Sport Coupi.
