Maria Michaela was caught after a BBC Crimewatch programme and she has been jailed for 9 years
Her crime was that of fraud perpetrated on HBOS and other banks, successfully conning them out of £13M. Her method was to "over-estimate prices for houses and then default on the mortgages." according to the BBC piece.
On the face of it this seems to be what the banks have been doing to the rest of us. The banks over estimated house prices on a gargantuan scale, and when they defaulted they were bailed out with the public purse. No banker has been prosecuted and indeed most have been unduly rewarded out of the public purse.
Not all the crooks are in it together. Some go to jail. Some are rewarded.
